1 FUNCTIONAL DESCRIPTION

1.1 FM Section

1.2 Mixer1, AGC and 1.IF

Mixer1 is a wide dynamic range stage with low noise and large input signal performance. The mixer1 tank can
be adjusted by software (IF1T). The AGC operates on different sensitivities and bandwidths (FMAGC) in order
to improve the input sensitivity and dynamic range (keying AGC). The output signals of AGC are controlled volt­age and current for preamplifier and pr estage pin diode attenuator.

Two 10.7MHz programmable amplifier s (IFG1, IFG2) correct the IF ceramic inser tion loss and the cos tumer lev­el plan application.

1.3 Mixer2, Limiter and Demodulator

In this 2. mixer stage the first 10.7MHz IF is converted into the second 450kHz IF. A multi-stage limiter generates
signals for the complete integrated demodulator without external tank. MPX output DC offset compensation is
possible by software (DEM).

(look at Figure 4)

1.4 Quality Detection and ISS

(look at Figure 2)

Fieldstrength

Parallel to mixer2 input a 10.7MHz limiter generates a signal for digital IF counter and a fieldstrength output sig­nal. This internal unweighted fieldstrength is used for keying AGC, adjacent channel and multipath detection
and is available at PIN14 (FSU) after +6dB buffer stage. The behaviour of this output signal can be corrected
for DC offset (SL) and slope (SMSL). The internal generated unweighted fieldstrength is filtered at PIN35 and
used for softmute function and generation of ISS filter switching signal for weak input level (sm).

Adjacent Channel Detector

The input of the adjacent c hannel detecto r is AC c oupled from i nter nal unweighted fiel dstrength. A programma­ble highpass or bandpass (ACF) and amplifier ( ACG) as well as rectifier determines the influences. This voltage
is compared with adjustable comparator1 thresholds (ACWTH, ACNTH). The output signal of this comparator
generates a DC level at PIN15 by programmable time constant. Time control (TISS) for a present adjacent chan­nel is made by charge and discharge current after comparator1 in an external capacitance. The charge current
is fixed and the discharge current is controlled by I

2

C Bus. This level produces digital signals (ac, ac+) in an
additional comparator4. The adjacent channel information is available as analog output signal after rectifier and
+8dB output buffer.

Multipath Detector

The input of the multipath detector is AC coupled from internal unwe ighted fieldstrength. A programm able band­pass (MPF) and amplifier (MPG) as well as rectifier determines the influences. This voltage is compared with
an adjustable comparator2 thresholds (MPTH). The output signal of this comparator2 is used for the "Milano"
effect. In this case the adjac ent channel detection is switched off. The "Milano" effect is selectable by I

2

C Bus

(MPOFF). The multipath information is available as analog output signal after rectifier and +8dB output buffer.

450kHz IF Narrow Bandpass Filter (ISS filter)

The device gets an additional second IF narrow bandpass filter for suppression nois e and adjacent channel sig­nal influences. This narrow filter has three switchable bandwidthes, narrow range of 80kHz, mid range of
120kHz and 30KHz for weather band information. Without ISS filter the IF bandwidth (wide range) is defined
only by ceramic filter chain. The filter is switched in after mixer2 before 450kHz limiter stage. The centre fre­quency and matching to the demodulator center frequency can be fine adjusted (AISS) by software..

Deviation Detector

In order to avoid distortion in audio output signal the narrow ISS filter is switched OFF for present overdeviation.

14/41

TDA7511

Hence the demodulator output signal is detected. A lowpass filtering and peak rectifier generates a signal that
is defined by software controll ed current (TDEV) in an external capac itance. This value is c ompared with a pro­grammable comparator3 thresholds (DWTH, DTH) and generates two digital signals (dev, dev+).

ISS Switch Logic

All digital signals coming fr om adjacent channel de tector, devia tion detector and softmute are ac ting vi a sw itch­ing matrix on ISS filter switch. The IF bandpass switch mode is controlled by software (ISSON, ISS30, IS S80,
ISSCTL). The switch ON of the IF bandpass is also available by manipulation of the voltage at PIN15. Two ap­plication modes are available (APPM). The conditions are described in table 37.

1.5 Soft Mute Control

The external fieldst reng th signal at PIN 35 is the ref erenc e for mute con trol. The startpoi nt, mute dep th and slop e
are progr ammable (SMTH, SM D, SLOPE) in a w ide range . The time c onstant i s define d by exter nal c apacit ance.
Additional adjacent channel mute function is supported. A highpass filter with -3dB threshold frequency of
100kHz, am plifie r and peak re ctifie r gen erates an adjac ent nois e sign al from MPX outp ut with th e same time co n­stant for sof tmute. Thi s value is compare d with compar ator5 thres holds (ACM). For present stron g adjacent cha n­nel the MPX signal is attenuated typical 6dB.

1.6 AM Section

The upconversion mixer1 is combined with a gain control circuit 1 sensing three input signals, narrow band in­formation at PIN 39, upconversion signal at PIN 58 and wide band information at PIN 3.This gain control circuit
gives two output signals. The first one is a current for pin diode attenuator and the second one is a voltage for
preamplifier. It is possible to put in a separate narrow bandpass filter before mixer2 at PIN 58. The intervention
point for first AGC (AMAGC) is programmable by software.

The oscillator frequency for mixer1 is generated by dividing the FM V CO frequency (AMD).
In mixer2 the IF1 is downconverted into the IF2 450kHz. Before the output signal reaches the 450kHz tank an

attenuator for IF gain control 2 is passed. Mixer1 and mixer2 tanks are software controlled adjustable
(IF1T, IF2T).

After filtering by ceramic filter a 450kHz amplifier with a gain control 3 is included. The gain control 2 and 3 are
the second AGC and programmable too by s oftware (DAGC). In or der to av oid an osc illation i n intervention point
it is important to know that the D AGC thr eshold has to be smaller than AMAGC! .

The demodulator is a peak detector. A further time constant with capacitor at pin40 produces a DC AGC refer­ence voltage depe ndent on input signal. The ti me c onstant i s s witchable by ratio of 30. This is necessary fo r the
station search function. The switching is software controlled (AMSEEK).

An internal comparator compares the AGC voltage with a programmable reference (AMSS). Consequently it is
possible to generate a seekstop impulse over a defined range.

A separate output is available for AMIF stereo or a permanent seek stop signal(SSTSEL).

1.7 PLL and IF Counter Section
PLL Frequency Synthesizer Block

This part contains a frequency synthesizer and a loop filter for the radio tuning system. Only one VCO is required
to build a complete PLL system for FM and AM upconversion. For auto search stop operation an IF counter
system is available.

The counter works in a two stages configurati on. The first stage is a swallow counter with a two modulus (32/33)
precounter. The second stage is an 11-bit programmable counter.

The circuit receives the sca ling factor s for the progr ammabl e counters and the val ues of the r eference frequen­cies via an I

2

C-Bus interface.The reference frequency is gener ated by an adjustable internal (XTA L) oscillator

followed by the reference divider. The reference and step-frequencies are free selectable (RC, PC).
Output signals of the phase detector are swi tching the programmable cur rent s ources. The l oop filter i ntegrates

their currents to a DC voltage.
The values of the current sour ces are programmable by 6 bits also r eceived via the I
To minimize the noise induced by the digital part of the system, a special guard area is implemented.
The loop gain can be set for different conditions by setting the current values of the chargepump generator.

Frequency Generation for Phase Comparison

The RF signals applies a two modulus counter (32/33) pre-scaler, which is controlled by a 5-bit divider(A). The
5-bit register (PC0 to PC4) controls this divider. In parallel the output of the prescaler connects to an 11-bit di­vider(B). The 11-bit PC register (PC5 to PC15) controls this divider

This phase error signal drives the charge pump current generator.

mode.
Few programmable phase errors (D0, D1) are available for inlock detection
The count of detected inlock informations, to release the inlock signal is adjustable (D2, D3), to avoid a switching

to low current during a frequency jump.

Low Noise CMOS Op -a mp

An internal voltage divider at pi n VREF2 connects the positi ve input of th e low n oise op-amp. The c harge pump
output connects the negative input. This inter nal ampli fier in cooperation w ith external components ca n provide
an active filter. The negative input is switchable to three input pins, to increase the flexibility in application. This
feature allows two separate active filters for different applications.

A logical "0" in the LP F register activates PIN LPFM, otherwise PI N LPAM is active. Whil e the high curre nt mode
is activated LPHC is switched on.

IF Counter Block

The input signal for FM and AM upconv ersion is the same 10.7MHz IF level after limiter . The grade of i ntegration
is adjustable by eight different measuring cycle times. The tolerance of the accepted count value is adjustable,
to reach an optimum compromise for search speed and precision of the evaluation.

For the FM range the center frequency of the measured count value is adjustable in 32 steps, to get the possi­bility of fitting the IF-filter tole rance. In the AM upconversion range an IF frequency of 10.689MHz to 10.720MHz
with 1kHz steps is available.

TDA7511

The IF -Counter Mode

The IF counter works in 2 modes controlled by IFCM register.

Sampling Timer

A sampling timer to generate the gate signal for the main counter is build wi th a 14-bit programmable counter
(IRC). In FM mode a 6.25kHz, in AM mode a 1kHz basically signal is generated. This is followed by an asyn­chronous divider to generate several sampling times.

Intermediate Frequency Main Counter

This counter is a 11 - 21-bit synchronous autoreload down counter. Five bits (CF) are programmable to have
the possibility for an adjust to the frequency of the IF-filter . The counter length is automatic adjusted to the cho­sen sampling time and the counter mode (FM, A M -UPC).

At the start the counter will be loaded with a defined value which is an equivalent to the divider value
(t

SamplexfIF

If a correct frequency is applied to the IF counter frequency input at the end of the sampling time the main
counter is changing its state from 0h to 1FFFFFh.

This is detected by a control logic and an external search stop output is changing from LOW to HIGH. The fre­quency range inside which a successful count result is adjustable by the EW bits.

The IF counter is only started by inlock information from the PLL part. It is enabled by software (IFENA).

Adjustment of the Measurement Sequence Time

The precision of the measurements is adjustabl e by contr oll ing the disc rimination window. This is adjustabl e by
programming the control registers EW0 to EW2.

The measurement time per cycle is adjustable by setting the Register IFS0 - IFS2.

Adjust of the Frequency Value

The center frequency of the discrimination window is adjustable by the control register CF0 to CF4.

TDA7511

1.8 I2C-Bus Interface

The TDA 7511 supports the I2C-Bus protocol. This protocol defines any device that sends data onto the bus as
a transmitter, and the receiving device as the receiver. The device that controls the transfer is a master and
device being controlled is the slave. The master will always initiate data transfer and provide the clock to trans­mit or receive operations.

Data Transition

Data transition on the SDA line must only occur w hen the clock SCL is LOW. S DA transitions while SCL is HIGH
will be interpreted as START or STOP condition.

Start Condition

A start condition is defined by a HIGH to LOW transition of the SDA line while SCL is at a stable HIGH level.
This "START" condition must precede any command and initiate a data transfer onto the bus. The TDA 7511
continuously monitors the SDA and SCL lines for a valid START and will not response to any command if this
condition has not been met.

Stop Condition

A STOP condition is defined by a LOW to HIGH transition of the SDA while the SCL line is at a stable H IGH
level. This condition terminates the communication between the devices and forces the bus-interface of the TDA
7511 into the initial condition.

Acknowledge

Indicates a successful data transfer . The transmitter will release the bus after sending 8 bits of data. During the
9th clock cycle the receiver will pull the SDA line to LOW level to indicate it receive the eight bits of data.

Data Transfer

During data transfer the TDA 7511 samples the SDA line on the leading edge of the SCL clock. Therefore, for
proper device operation the SDA line must be stable during the SCL LOW to HIGH transition.

Device Addressing

To start the communication between two devices, the bus master must initiate a start instructi on sequence, fol­lowed by an eight bit word corresponding to the address of the device it is addressing.

The most significant 6 bits of the slave address are the device type identifier.
The TDA 7511 device type is fixed as "110001".
The next significant b it is used to addres s a partic ular devic e of the previ ous defin ed type co nnected to the bus.
The state of the hardw ired PI N 41 defines the s tate of this addr ess bit . So up to two devices could be connected

on the same bus. When PIN 41 is connected to VCC2 the address bit “1” is selected. In this case the AM part
doesn’t work. Otherwise the address bit “0” is selected (FM and AM is working). Therefor a double FM tuner
concept is possible.

The last bit of the start instruction defines the type of operation to be performed:

- When set to "1", a read operation is selected

- When set to "0", a write operation is selected
The TDA 7511 connected to the bus will compare their own hardwired address with the slave address being

transmitted, after detecting a START co ndition. After this comparis on, the TD A 7511 wi ll generate an "acknow l­edge" on the SDA line and will do either a read or a write operation according to the state of R/W bit.

18/41

TDA7511

Write Operation

Following a START condition the master s ends a s lave addres s w ord with the R/W bit set to "0". The TDA 7511
will generate an "acknowledge" after this firs t transmission and will wait for a second word (the word addr ess
field). This 8-bit address field provides an access to any of the 32 internal addresses. Upon receipt of the word
address the TDA 7511 slave device will respond with an "acknowledge". At this time, all the following words
transmitted to the TDA 7511 will be considered as Data. The internal address will be automatically in cremented.
After each word receipt the TDA 7511 will answer with an "acknowledge".

Read Operation

IF the master sends a slave address word with the R/W bit set to "1", the TDA 7511 will transit one 8-bit data
word. This data word includes the following informations:

bit0 (ISS filter, 1 = ON, 0 = OFF)
bit1 (ISS filter bandwidth, 1 = 80kHz, 0 = 120kHz)
bit2 (MPOUT,1 = multipath present, 0 = no multipath)
bit3 (1 = P LL is locked in , 0 = PLL is locked out).
bit4 (fieldstrength indicator, 1 = lower as softmute threshold, 0 = higher as softmute threshold)
bit5 (adjacent channel indicator, 1 = adjacent channel present, 0 = no adjacent channel)
bit6 (deviation indicator, 1 = strong overdeviation present, 0 = no strong overdeviation)
bit7 (deviation indicator, 1 = over deviation present, 0 = no overdeviation)
