LA75521VA
Overview
The LA75521VA is a fully adjustment-free VIF + SIF signal processing IC for TV sets and VCRs that supports the PAL
video standard. It supports 38.0MHz, 38.9MHz, and 39.5MHz as the IF frequencies, as well as PAL sound multi-system
(M/N, B/G, I and D/K), and contains an on-chip sound carrier trap. The IC employs a 4MHz frequency (which can be
switched to 4.43MHz) as the reference frequency of the adjustment free circuit, and controls the VCO, AFT, and sound
filter using an external input signal.
Features
• Internal VCO adjustment free circuit eliminating the need for an external VCO coil.
• Internal sound carrier trap enables easy configuration of PAL sound multi-system at low cost.
• Considerably reduces the number of required peripheral parts.
• Use of digital AFT eliminates a problem of AFT tolerance.
• Package: SSOP24(225mil)
Functions
• VIF amplifier
• EQAMP
• Adjustment-free VCO and PLL detector circuit
• Internal sound carrier trap
• Digital AFT circuit
• First SIF detector circuit
• RF AGC
• PLL-FM detector circuit
• Buzz canceller
Ordering number : EN*A1004
