CXA1702AR

4-channel REC/PB Amplifier for 8 mm VCR

Description

The CXA1702AR is a bipolar IC designed as

recording/playback amplifiers for Hi8-compatible

VCRs.

64 pin LQFP (Plastic)

•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.
