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.

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.

Functions
• Audio FM modulator.
• Sync pulse peak clamp.
• White clip.
• Voltage regulator.
