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.

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.

Functions

• Audio FM modulator.

• Sync pulse peak clamp.

• TSG.

• White clip.

• Voltage regulator.
