Monolithic Linear IC
Video, Audio Signal Processor
for UHF Band RF Modulator Use
Ordering number:ENN2856C
LA7054Z
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LA7054Z 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. The characteristics of the LA7054Z
are highly stable to supply voltage variations because the
LA7054Z 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
LA7054Z has an internal voltage regulator.
• On-chip TSG (test signal generator).
• Good frequency characteristic of white clip.
• Large amplitude of audio carrier and less high-frequency
spurious radiation.
• Low audio distortion.
• Low current drain : –30% (compared with our similar
ICs).
• Minimum number of parts required : Peripherals of clock
oscillator for TSG.
• Compact package : 9Z-pin SIP.
