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.

The chip has an ‘easy programming’ mode to make the I²C-bus protocol very simple. In

principle, only one bit sets the proper standard with recommended content. However, if

this is not suitable, free programming is always possible.

2. 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 application effort and external component count in combination with the

TDA8275A or TDA1827x

I Pin compatible with predecessor TDA8290

I Simple upgrade of TDA8290 possible

I 12-bit IF ADC on chip running with 54 MHz or 27 MHz

I Two 10-bit DACs on chip for CVBS and SSIF or audio

I Easy programming for I²C-bus

I High ﬂexibility due to various I²C-bus programming registers

I I²C-bus interface and I²C-bus feed-through for tuner programming

I Four I²C-bus addresses selectable via two external pins
