Monolithic Linear IC
Video, Audio Signal Processor
for UHF Band RF Modulator Use
Ordering number:ENN2857A
LA7058R
SANYO Electric Co.,Ltd. Semiconductor Company
TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN
Overview
The LA7058R, being a video/audio signal processor IC for
UHF band RF modulator use, is suited for RF modulators
that require no TSG (test signal generator). The LA7058R
contains a video clamp circuit, a white clip circuit, and an
audio FM modulator. The characteristics of the LA7058R
are highly stable to supply voltage variations because of
the on-chip voltage regulator.
Functions
• Audio FM modulator.
• Sync pulse peak clamp.
• White clip.
• Voltage regulator.
Features
• Capable of being operated from low supply voltage
(VCC=5V).
• Highly stable to supply voltage variations because of onchip voltage regulator.
• Excellent 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 external parts required.
• Small-sized package : 9Z-pin SIP.
