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 on-
chip 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.
