Monolithic Linear IC
LA7054
Video, Audio Signal Processor
for UHF Band RF Modulator
Overview
The LA7054 is a video, audio signal processor IC for UHF band RF modulators. It performs the functions of TSG (test signal generator), video clamp circuit, white clip circuit, audio FM modulator. It is highly stable to supply voltage variations because the LA7054 has an internal voltage regulator.
Functions
•Audio FM modulator
•Sync pulse peak clamp
•TSG
•White clip
•Voltage regulator

3017C-SIP9
[LA7054]
SANYO: SIP9
Features
•Low-voltage operation : VCC=5V
•Highly stable to supply voltage variations because the LA7054 has an internal voltage regulator.
•On-chip TSG (test signal generator).
•Good frequency characteristic of white clip.
•Wide amplitude of audio carrier and less high-frequency spurious interference.
•Low audio distortion.
•Low current drain : –30% (compared with our similar ICs).
•Minimum number of parts required : Peripherals of clock oscillator for TSG.
•Small-sized package : 9-pin SIP
