1 / 6 page Overview The LA7688 integrates VIF, SIF, video, chrominance, and deflection processing circuits for PAL/NTSC format TV sets on a single chip and is provided in a 52-pin shrink package. The VIF and SIF circuits achieve semi-adjustment-free operation, and are adjustment-free except for the VCO coil and the RF AGC circuit. The chrominance circuit can be made adjustment-free by using the LC89950 1H delay line IC. All the signal processing required for a multi-format color TV can be implemented by combining this product with the LA7642 SECAM decoder IC. Features [VIF] • PLL detector • Buzz canceller [SIF] • PLL detector • Audio switch [VIDEO] • Built-in trap • Built-in DL • Aperture control • Video switch (SVO output) • Black expansion [CHROMA] • PAL/NT • Base band processing (adjustment free) • Built-in bandpass filter [OSD] • Analog OSD [DEF] • Automatic 50/60 Hz discrimination • Fixed vertical size • Double AFC • Built-in sync separator circuit [Other features] • Sandcastle pulse (for the 1H delay line) • fsc output (for SECAM systems) • Primary color output Package Dimensions unit: mm 3218-DIP52S Monolithic Linear IC Ordering number : EN5635 82097HA(OT) No. 5635-1/6 SANYO: DIP52S [LA7688] SANYO Electric Co.,Ltd.
