Monolithic Linear IC
LA75503V
Adjustment Free VIF/SIF Signal Processing IC
for PAL TV/VCR
Overview
The LA75503V is an adjustment free VIF/SIF signal
processing IC for PAL TV/VCR.
It supports 38 MHz, 38.9 MHz, and 39.5 MHz 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, 4-MHz external crystal or 4-MHz
external signal is needed.
Functions
• VIF amplifier
• VCO adjustment free PLL detection circuit
• Digital AFT circuit
• RF AGC
• Buzz canceller
• Equalizer amplifier
• Internal sound carrier BPF
• Internal sound carrier trap
• PLL-FM detector
• Reference oscillation circuit
Features
• 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)
