LA75503V

Overview

Features

Functions

The LA75503V is an adjustment free VIF/SIF signal processing IC for PAL TV/VCR. It supports 38MHz, 38.9MHz, and

39.5MHz as the IF frequencies, as well as PAL sound multi-system (M/N, B/G, I, D/K), and contains an on-chip sound

carrier trap and sound carrier BPF. To adjust the VCO circuit, AFT circuit, and sound filter, 4MHz external crystal or

4MHz external signal is needed.

• Internal VCO adjustment free circuit eliminating need for VCO coil adjustments.

• Internal sound carrier BPF and sound carrier trap enable easy configuration of PAL sound multi-system at low cost.

• Considerably reduces the number of required peripheral parts.

• Use of digital AFT eliminates problem of AFT tolerance.

• Package: SSOP30 (275 mil)

• VIF amplifier

• VCO adjustment free PLL detection circuit

• Digital AFT circuit

• RF AGC

• Buzz canceller
