TDA8260TW Datasheet Satellite Zero-if Qpsk/8psk Downconverter With Pll Synthesizer

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TDA8260TW Satellite Zero-IF QPSK/8PSK downconverter with PLL synthesizer Product specification Supersedes data of 2003 Jun 11 2004 Sep 03 Philips Semiconductors Product specification.

General Description

The direct conversion QPSK demodulator is the front-end receiver dedicated to digital TV broadcasting, satisfying both DVB and DBS TV standards.

The wide range oscillator (from 950 to 2175 MHz) covers the American, European and Asian satellite bands, as well as the SMA-TV US standard.

The Zero-IF concept discards traditional IF filtering and intermediate conversion techniques.

Key Features

  • Direct conversion Quadrature Phase Shift Keying (QPSK) and 8-Phase Shift Keying (8PSK) demodulation (Zero-IF).
  • Frequency range: 950 to 2175 MHz.
  • High level asymmetrical RF input.
  • 0 to 50 dB variable gain with AGC control.
  • Loop-controlled 0 to 90° phase shifter.
  • High AGC linearity (.
