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
signal generator), video clamp circuit, white clip circuit, ^3017C-SIP9
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
Features
• Low-voltage operation : V_CC=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
