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
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
