C8225 series is a pulse generator specifically designed for NMOS linear image sensor driver circuits. C8225 series provides the driver circuits

with a master start pulse and master clock pulse which can be preset by rotary switches.

C8225 series uses a quartz oscillator as the reference clock that delivers high-precision master start and clock pulses. When a separate pin connector

and socket are installed on the circuit board, C8225 series can be mounted directly on C7883/C7884/C7885 series image sensor driver circuit board.

Features

l Directly mountable on C7883/C7884/C7885 series

l Compact (compared to conventional type C4091)

l Single power supply (+5 V) operation

Description

Feature

C8225-01

For C7883/C7884 series

Master start interval: 1 µs to 50 s (1-2-5 sequence)

Master clock frequency: 62.5 kHz to 32 MHz

Has no input/output connector.

C8225-02

For C7885 series

Master start interval: 1 µs to 50 s (1-2-5 sequence)

Master clock frequency: 46.875 kHz to 24 MHz

Has no input/output connector.

Note)

1: Standard input/output connector is FAP-16-07#2 (made by Yamaichi, sold separately). Equivalent connectors are available

from other manufacturers.

2: When mounting C8225 series on a driver circuit, use a 6-pin socket (PM-1 made by MAC8) on the driver circuit and a 6-pin

plug (OY-003 made by MAC8) on C8225 series.

3: Custom products with an input/output connector pre-mounted are available on request. Please consult our sales office.

4: We welcome custom requests. Feel free to contact our sales office.
