Sipex SP322 V.11/V.35 Serial Transceiver Datasheet
The SP322 is a programmable V.11/V.35 transceiver IC. It contains three drivers and three receivers that can be selected via a V.11/V.35 select pin, offering up to 10 Mbps data rates while complying with ITU specifications. The device includes internal resistor termination for V.35 operation and optional cable termination for V.11 mode, with enable pins that place outputs in a high‑impedance state for flexible DTE/DCE configurations.
Electrical characteristics such as supply voltage (+4.75 V to +5.25 V), low shutdown current (4 pA), and maximum transmission rate (10 Mbps) are detailed, along with package information (44‑pin MQFP) and ordering options, including lead‑free variants. The datasheet provides test circuit diagrams, switching waveforms, and timing specifications for both driver and receiver sections.
