Preliminary specification
TDA8415
GENERAL DESCRIPTION
The TDA8415 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 TDA8415 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
Function and software are compatible with the TDA8405
Two general purpose output ports
Full ESD protection
