Preliminary specification

TDA8416

GENERAL DESCRIPTION

The TDA8416 is a processor of stereo/dual language

signals (B/G-standard) for stereo sound television

receivers and VTRs, using the switched-capacitor

technique. The AF signals at the TDA8416 inputs must be

“(L+R)/2” or “language A” on one channel and “R” or

“language B” on the second channel (where L = left and

R = right). The carrier frequency of the second channel is

also modulated by an identification signal (stereo or dual

sound). The device is controlled by a microcomputer via

the two-line, bidirectional I2C-bus.

Features

• Use of the switched-capacitor technique for signal

processing

• Small amount of peripheral components

• Integrated anti-aliasing filters

• Low distortion AF signal handling

• Integrated de-emphasis with a time constant of 50 µs

• Two general purpose output ports

• Full ESD protection
