Overview
INTEGRATED CIRCUITS DATA SHEET TDA8417 TV and VTR stereo/dual sound processor with integrated filters and I2C-bus control Preliminary specification File under Integrated Circuits, IC02 September 1989 Philips Semiconductors Preliminary specification TV and VTR stereo/dual sound processor with integrated filters and I2C-bus control TDA8417 GENERAL DESCRIPTION The TDA8417 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 TDA8417 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 QUICK REFERENCE DATA PARAMETER Supply voltage (pin 15) Supply current (pin 15) AF output signal (RMS value) (pins 11 to 14) Weighted signal-to-noise ratio of the AF output signals (CCIR 468/3) Crosstalk attenuation stereo mode at dual sound mode at Pilot signal input sensitivity Total harmonic distortion PACKAGE OUTLINE 20-lead DIL; plastic (SOT146); SOT146-1; 1996 November 18 f = 1 kHz f = 40 Hz to 12.
