DESCRIPTION

The FM1236/F H-3 family belongs to the new FM1200 MK3 family of small size frontends, which are designed

Multi-Media environment. The FM1236/F H-3 combines the functions of tuner, and a NTSC demodulation unit.

The frontends have a built-in digitally (I2C) PLL tuning system. A DC-DC converter circuit is built-in in the FM1236/F H-3 to synthesize the tuning voltage required, thus making the frontend a true 5V device.

The following items of information are printed on a sticker that is on the top cover of the tuner:

• Type number

• Code number

• Origin letter of factory

• Change code

• Year and week code

DEMONSTRATION KIT A demonstration kit is available for the FM1236/F H-3 (software, Application Note and evaluation board).

Please contact your local Sales Engineer for details about the price and availability I2C PROGRAMMING For information regarding general aspects of I²C bus control see 'The I2C-bus and how to use it', published by

Philips Semiconductors under the code : 9398 393 40011. The FM1236/F H-3 contains two I2C transceivers, one in the tuner part and one in the IF part. It is imperative to ensure that both I2C devices are programmed correctly according to their addresses

Note: For TV Mode: FIF = 45.75 MHz, For FM Radio Mode: FIF = 10.7 MHz

CONTROL BYTE CB Charge Pump Setting: CP can be set to either 0 (low current) or 1 (high current).

CP = 1, charge pump current = 280uA results in fastest tuning (default mode) CP = 0 , charge pump current = 60uA results in moderate speed tuning with slightly better residual oscillator FM. It is recommended to set CP=0 in the FM mode at all times.

Test Mode Setting: T2 = 0, T1 = 0, T0 = 1 for normal operation (default) T2 = 0, T1 = 1, T0 = 1 indicates that Byte AB will follow Byte CB instead of Byte BB for the current IIC Byte

sequence.

2). The AGC detector is disabled and I AGC = 9 µA.

It is recommended to set the TOP at 109 dBµV FOR NTSC M systems. For FM radio, it is also recommended to set the TOP to 109 dBµV.

The following data can be read from the device through the status byte: POR (power on reset): POR is internally set to 1 in case Vcc drops below 3V. The POR bit is reset when an

end of data is detected by the PLL-IC. FL: in lock flag (FL = 1 when the phase lock loop is in lock).

The loop must be phase-locked during at least 8 periods of the internal 7.8125 kHz reference-frequency (i.e. 1 msec) before the FL flag is internally set to 1.

AGC : internal AGC flag. AGC=1 when internal AGC is active (level below 3V)

A2, A1, A0 : Used for indicating if the FM signal received is transmitted in stereo or mono. If A2 =1and A1=A0=0, then the signal is in stereo, otherwise, it is mono.

PROGRAMMING EXAMPLES

Example 1: To tune to Ch A14 (471.25 MHz) in high band Fosc = 471.25 + 45.75 = 517.00 MHz

N = (517.00 MHz) / (62.5 kHz) = 20 50 (Hexadecimal) So DB1 = 20 H and DB2 = 50 H CB = 86H if CP is set to low or CB = C6H if CP is set to high BB = 44 H (because of high band selected)

Tuner I2C program

IF I2C program

Note: Stereo Mode and Normal FM Sensitivity has been selected.

Important:

When tuning to a desired FM channel,it is recommended first to set to the TV mode at a high frequency (e.g.150 MHz), then set to FM mode (IF=10.70 MHz) and then set to the desired FM station. This is to ensure that the tuning voltage does not stay locked at 0V.

QSS Desktop Video & FM Radio Module FM1236/F H-3

LOADING OF I2C BUS

The FM1236/F H-3 contains a series impedance R= 200 ohms in the SCL and SDA lines. Both lines also have capacitive loads of C= 22 pF max. Care must be taken to ensure that the total load on the bus does not exceed that as mentioned in the brochure "The I2C-bus and how to use it".

CVBS LOAD / TUNING VOLTAGE SUPPLY

A video buffer is built into the frontend to enable the unit to drive a 75 Ω load directly (e.g. into the SAA711x directly). A DC-DC converter for providing the required tuning voltage supply is already built into the FM1236/F H-3.

AUDIO OUTPUT AT PINS 9 & 10

The pins 9 and 10 are used to provide the FM radio stereo outputs AF_L and AF_R. For TV sound, the MONO output is also available at these 2 pins.

MECHANICAL DATA

See product drawing 3139 149 0120

Standard F sockets female 75Ω.

SOLDERABILITY

The solderability of pins and mounting tags when tested initially and after 16 hour steam ageing in accordance with “IEC 60068-2-20”, test Ta, method 1 (solder bath 235°C for 2s), results in a wetted area of 95%. No de-wetting will occur when soldered at 260°C for 5s.

RESISTANCE TO SOLDERING HEAT

The product will not be damaged when tested in accordance with “IEC 60068-2-20”, test Tb, ,method

1A (solder bath 260°C for 10±1 s).

MASS

Approximately 45g.

The products are packed in the carton box and transferred to customers by Pallet Transport.

The pins will not be damaged when tested in accordance with “IEC 60068-2-21”:

• Test Ua1, tensile of 10N in axial direction

• Test Ua2, thrust of 4N in axial direction

PUNCHING PATTERN OF CHASSIS PCB

For optimum mounting of the tuner to a PCB, the punching pattern is recommended (see 3139 149 0120).

The tuner must be mounted without clearance between the tuner supporting surface and the printed circuit board (PCB). When mounted in this way, the tuner must be soldered to the PCB. This can be achieved by pressing the unit vertically onto the PCB during soldering.
