LA7054
Video, Audio Signal Processor for UHF Band RF Modulator
Overview
Package Dimensions
The LA7054 is a video, audio signal processor IC for UHF unit: mm band RF modulators. It performs the functions of TSG (test 3017C-SIP9 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
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
