Description
The CXA1702AR is a bipolar IC designed as recording/playback amplifiers for Hi8-compatible VCRs.

Features
• Recording/playback system
    • Hi8-compatible wideband recording/playback amplifier.
    • Enables electric variable resistor (EVR) control.

• Recording system
    • Feedback damping provided in the recording amplifier and its EVR control function facilitate printed circuit board design.
    • Five-input (Y, chroma, AFM, ATF, PCM) mix amplifier and EVR control function for Y/low-band recording level.
    • Ramp circuit for the recording amplifier output bias current.

• Playback system
    • Feedback dumping provided in the playback amplifier facilitates printed circuit board design.
    • Middle-frequency tuner on chip; EVR permits independent adjustment of its center frequency fo, Q and boost amount by EVR.
    • RF AGC and dropout detection circuit.

Application
    8 mm VCR
