描述 Description

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

特性 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
