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.
