TDA8042M - Quadrature demodulator

Description

The TDA8042M is a monolitic bipolar IC dedicated for BPSK and QPSK demodulation.

It is designed to be used together with the TDA8043 as part of a complete BPSK/QPSK satellite demodulator and decoder.

The bandwidth of the TDA8042M allows symbol rates up to 45 Msymbols/s.

Features

  • 5 V supply voltage.
  • Internal voltage reference.
  • 350 to 650 MHz input frequency range.
  • On-chip 0° and 90° phase shifter.
  • Symbol rate up to 45 Msymbols/s.
  • High input sensitivity.
  • Built-in voltage stabilizer.
  • AGC amplifier with 21 dB control range.
  • AGC detector.
