TDA8261TW Datasheet Satellite Zero-if Qpsk/8psk Downconverter With Pll Synthesizer

Manufacturer: NXP Semiconductors

Overview: INTEGRATED CIRCUITS DATA SHEET TDA8261TW Satellite Zero-IF QPSK/8PSK downconverter with PLL synthesizer Product specification Supersedes data of 2004 Oct 25 2004 Dec 02 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 Satellite Master Antennae (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 8PSK demodulation (Zero-IF).
  • 950 to 2175 MHz frequency range.
  • High-level asymmetrical RF input.
  • 0 to 50 dB variable gain on RF input.
  • Loop-controlled 0° to 90° phase shifter.
  • High AGC linearity (.
