Description
CXA1202Q-Z/CXA1202R are bipolar ICs developed as REC/PB amplifiers for VCRs.
FEATUREs
• Built-in head amplifier feedback dumping contributes 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.
APPLICATIONs
• 8-mm system VCR
• β-system VCR
• VHS-system VCR
