AN5870K

Wide bandwidth analog switch IC

■ Overview

The AN5870K is a wide bandwidth analog switch IC
of 300 MHz operation. It is usable for RGB signal and
horizontal/vertical synchronizing signals, and it has a
built-in 75 Ω driver for video signal. In addition, it has
also realized a high speed operation by the adoption of
CMOS process for its sync. signal processing circuit. It is
usable in a broad range from a popular type monitor to a
high definition monitor.

■ Features

• 2-input 1-output circuit (DC switch type)

• Built-in 6 dB amplifier for RGB signal (1.5 dB for 75
Ω termination)

• Built-in sync. separation circuit (Supporting sync. on

green and power save)

• Higher speed horizontal / vertical sync. signal circuit
