Monolithic Linear IC
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.
