GENERAL DESCRIPTION

The ADM1345 is a line transmitter/receiver that can send

and receive the differential clock and data signals for a

V.35 interface while requiring only a single +5V supply.

The device contains three current output differential line

PRELIMINARY

transmitters, three differential receivers, and a charge

pump to generate an on-chip negative supply.

TECHNICAL

The ADM1345 operates at data rates up to 10Mbaud.

DATA

Transmitter outputs are short-circuit protected and are

failsafe, assuming a high impedance state when the trans-

mitters are disabled, the device is shut down, or the power

is off. A Receiver Output Enable pin allows the receiver

outputs to be forced into a high impedance state.

The receiver inputs and transmitter outputs are both pro-

tected against repeated electrostatic discharge (ESD) up to

± 10kV.

OE 14

A complete DCE or DTE V.35 port can be implemented

using only an ADM1345 and 4 x 1µF capacitors for the

charge pump, an external resistor termination network,

and an ADM208E for the control signals.
