M52769FP
PLL-SPLIT VIF/SIF
DESCRIPTION
M52769FP is a semiconductor integrated circuit consisting of VIF/SIF signal processing
for CTVs and VCRs. M52769FP corresponds to FM radio and provide low cos t and high
performance system with the coil-less AFT.
FEATURES
FM radio receiving is available without FM radio IC and external filter
Built-in FM radio carrier indicator
Coil-less AFT.
The PLL-SPLIT system provides good sound sensitivity and reduces buzz.
Video output is 2.0Vp-p through EQ AMP.
Built-in QIF AGC.
Improve over modulation characteristics and Vcc ripple rejection.
