TDA8262HN

The TDA8262HN is designed as one kind of fully integrated satellite tuner device that is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB-S and DBS TV standards. And this device has four selectable I2C-bus addresses. Applying a specific voltage to pin AS selects an address. Also this device can be used in (1)Direct Broadcasting Satellite (DBS) QPSK demodulation; (2)Digital Video Broadcasting (DVB) QPSK demodulation; (3)BS digital 8PSK demodulation; (4)DVB-S2 8PSK demodulation applications.

Features of the TDA8262HN are:(1)Direct conversion QPSK and 8PSK demodulation (ZIF); (2)3.3 V DC supply voltage (no 30 V required); (3)950 MHz to 2175 MHz frequency rangecomparable to QSS single reference concepts; (19)AM/FM mono sound demodulator; (4)Low noise RF input (integrated LNA); (5)0 dB to 55 dB continuous variable gain on RF input; (6)RF input level detector; (7)Switchable 0 dB to 9 dB additional gain on baseband output amplifier; (8)Programmable 5 MHz to 36 MHz 5th-order baseband filters for I and Q paths; (9)Fully integrated PLL frequency synthesizer; (10)Low phase noise fully integrated oscillator; (11)Operation from a 16 MHz crystal or external clock; (12)5 frequency steps from 125 kHz to 2 MHz; (13)Crystal frequency output to drive the demodulator IC.

The absolute maximum ratings of the TDA8262HN can be summarized as:(1)supply voltage: 3.15 to 3.45 V;(2)supply current: 167 mA;(3)oscillator frequency: 950 to 2175 MHz;(4)absolute quadrature error: 0 to 5 degree;(5)LPF cut-off frequency: 5 to 36 MHz;(6)amplifier gain control range: 55 to 60 dB;(7)ambient temperature: -20 to +85 °C.
