TDA8295 - Digital global standard low IF demodulator

General Description

The TDA8295 is an alignment-free digital multistandard vision and sound low IF signal PLL demodulator for positive and negative video modulation including AM and FM mono sound processing.

It can be used in all countries worldwide for M/N, B/G/H, I, D/K, L and L-accent standard.

Key Features

  • I Digital IF demodulation for all analog TV standards worldwide (M/N, B/G/H, D/K, I, L and L-accent standard) I Multistandard true synchronous demodulation with active carrier regeneration I Alignment-free I 16 MHz typical reference frequency input (from low IF tuner) or operating as crystal oscillator I Internal PLL synthesizer which allows the use of a low-cost crystal (typically 16 MHz) I Especially suited for the NXP Silicon Tuner TDA8275A or TDA1827x I No SAW filter needed I Low.

TDA8295 Digital global standard low IF demodulator for analog TV and FM radio Rev. 01 — 4 February 2008 Product data sheet 1. General description The TDA8295 is an alignment-free digital multistandard vision and sound low IF signal PLL demodulator for positive and negative video modulation including AM and FM mono sound processing. It can be used in all countries worldwide for M/N, B/G/H, I, D/K, L and L-accent standard. CVBS and SSIF/mono audio is provided via two DACs. FM radio preprocessing is included for simple interfacing with demodulator/stereo decoder backends. The IC is especially suited for the application with the NXP Silicon Tuner TDA8275A or TDA1827x. All the processing is done in the digital domain.
