For the availability of this product, please contact the sales office.
Description
CXA1202Q-Z/CXA1202R are bipolar ICs developed
as REC/PB amplifiers for VCR's.
CXA1202Q-Z
48 pin QFP (Plastic)
CXA1202R
48 pin LQFP (Plastic)
Features
• Built-in head amplifier feedback dumping con-
tributes to the reduction of external components
and simplification of the print circuit board design.
• Built-in BPF for PB signals medium range frequency
compensation totally eliminates external resonance
circuits (L. C. R.)
• Low range recording signal variable-level mix
amplifier allows for both metal powder and metal
evaporated tapes application.
• Consumption saving through power save function
of the REC AMP.
• 4-head system switch incorporated.
Functions
• Recording: 2-channel REC AMP, 5-input (Y, Chroma, AFM, ATF, PCM) Mix AMP.
• Playback: 2-channel low-noise head amplifier, medium range frequency compensation circuit, RF AGC,
dropout detecting circuit.
