Pin5:FB

Feedback Input. FB senses the output voltage to regulate that voltage. Drive FB with a
resistive voltage divider from the output voltage. The feedback threshold is 1.222V.

Pin6:COMP

Compensation Node. COMP is used to compensate the regulation control loop. Connect
a series RC network from COMP to GND to compensate the regulation control loop. In
some cases, an additional capacitor from COMP to GND is required.

Pin7:EN

Enable Input. EN is a digital input that turns the regulator on or off. Drive EN high to turn
on the regulator, drive EN low to turn it off. An Under Voltage Lockout (UVLO) function
can be implemented by the addition of a resistor divider from VIN to GND. For complete
low current shutdown its needs to be less than 0.7V. For automatic startup, leave EN
unconnected.

15.2. DRX 3973D

Fourth-Generation COFDM Demodulators

15.2.1 Introduction

The DRX 3973D and the DRX 3977D are fourth-generation COFDM demodulators that offer today’s
highest level of front-end integration resulting in ultimate DVB-T digital reception, compliant to ETS 300
744, DTG D-Book, EICTA E-Book, and Nordig Unified v1.0.2 .

The DRX 3973/77D applies cutting-edge digital filtering techniques in combination with a high­performance A/D-converter and PLL configuration, resulting in superior performance figures in the
presence of digitaland analog adjacent channels.

Progressive channel estimator algorithms provide exceptional performance in multipath- and dynamicecho
conditions – an especially important feature for single-frequency networks and indoor reception.

The state-of-the-art impulsive noise cruncher suppresses interferences originating from sources such as
cars, electrical motors, and household appliances.

 Highest level of front-end integration and flexibility:

 Integrated PGA (programmable gain amplifier) 30 dB
 Single 8 MHz SAW filter operation
 2 AGC control signals available for RF and IF amplifier control
 Flexible clock reference options
 Re-use of 4 MHz tuner clock reference
 Pre-SAW sense input for optimal RF AGC setting and RF-level measurement

 Excellent digital reception performance:

 Superior digital and analog adjacent channel performance (> 40dB for QEF)
 Impulsive noise cruncher

 Multipath and dynamic echoes
 The input IF frequency ranging up to 44 MHz ensures upward compatibility for new tuner topologies
 Integrated microprocessor to perform autonomous detection and operation of all possible DVB-T

modes, without interaction with the host processor

 Fully automatic and fast signal acquisition: UHF and VHF band-scan in <20 seconds
 Meets all international DVB-T receiver specifications: Nordig Unified, DTG, EICTA
 Comfortable software drivers for integration of tuner and COFDM demodulator
 Secondary serial interface for tuner control
 5 V tolerant AGC and secondary serial protocol outputs
 2 general purpose I/O pins (GPIO)
 Configurable parallel or serial MPEG-TS output
 PMQFP64-2 package: footprint 1010 mm (DRX 3973D)
 PQFN48-1 package: small footprint 77 mm (DRX 3977D)
 IEEE 1149.1 boundary scan

 PVR / DVDR
 Network interface modules (NIM)
 PC-TV applications

15.3. PI6CX100-27

27 MHz 3.3V VCXO for Set-Top Box Applications

15.3.1 Features

• 3.3V operating voltage

• Uses an inexpensive external crystal

• On-chip VCXO with pull range of 240ppm

• VCXO tuning voltage from 0 to 3.3V

• 10mA output drive at CMOS levels

• Available in SOIC package

15.3.2 Description

The PI6CX100-27 is a low-cost, high-performance 3.3V VCXO, designed to replace expensive VCXO
modules. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3.3V input voltage to cause
clocks to vary by ±120ppm. This device uses an inexpensive external pullable crystal at 27 MHz to
produce the same output frequency.The PI6CX100-27 is designed for Set-Top Box applications.

2MOS technology.

15.5. FMS6145

Low Cost Five Channel 4th Order Standard Definition Video Filter Driver

15.5.1 Features

x Five fourth-order 8MHz (SD) filters
x Transparent input clamping
x Dual video load drive (2Vpp, 75)
x AC or DC-coupled inputs
x AC or DC-coupled outputs
x DC-coupled outputs eliminate AC-coupling capacitors
x 5V only
x Lead (Pb) Free TSSOP-14 package

15.5.2 Applications

x Cable set top boxes
x Satellite set top boxes
x DVD players
x HDTV
x Personal video recorders (PVR)
x Video on demand (VOD)

15.5.3 Description

The FMS6145 Low Cost Video Filter (LCVF) is intended to replace passive LC filters and drivers with a
low-cost integrated device. Five 4th order filters provide improved image Quality compared to typical 2nd
or 3rd order passive solutions.

The FMS6145 may be directly driven by a DC-coupled DAC output or an AC-coupled signal. Internal
diode clamps and bias circuitry
may be used if AC-coupled inputs are required.

The outputs can drive AC or DC-coupled single (150) or dual(75) loads. DC-coupling the outputs
removes the need for output coupling capacitors. The input DC levels will be offset approximately +280mV
at the output.

15.6. MP1593

3A, 28V Step-Down Converter

15.6.1 Description

The MP1593 is a step-down regulator with an internal Power MOSFET. It achieves 3A
continuous output current over a wide input supply range with excellent load and line regulation.

Current mode operation provides fast transient response and eases loop stabilisation. Fault
condition protection includes cycle-by-cycle current limiting and thermal shutdown. Adjustable
soft-start reduces the stress on the input source at turn-on. In shutdown mode the regulator
draws 20μA of supply current.

The MP1593 requires a minimum number of readily available external components to complete
a 3A step down DC to DC converter solution.

15.6.2 Features

x 3A Output Current
x Programmable Soft-Start
x 100m Internal Power MOSFET Switch
x Stable with Low ESR Output Ceramic Capacitors
x Up to 95% Efficiency
x 20μA Shutdown Mode
x Fixed 385KHz Frequency

x Thermal Shutdown
x Cycle-by-Cycle Over Current Protection
x Wide 4.75 to 28V Operating Input Range
x Output Adjustable from 1.22Vs
x Under Voltage Lockout
x Available in 8-Pin SOIC Package

15.6.3 Applications

x Distributed Power Systems
x Battery Chargers
x Pre-Regulator for Linear Regulators
x Flat Panel TVs
x Set-Top Boxes
x Cigarette Lighter Powered Devices

x DVD/PVR Devices
