P/ACTIVE V.35 TERMINATION NETWORK
Features
Stable resistor network
6 terminations/package
Separate ground for receive terminations
Version for receiver input impedance compensation
Saves board space and reduces assembly cost
Product Description
The PACV35 termination network is an integrated resistor interface used to ensure proper signal integrity between transmit-
ter and receiver sections for V.35 protocols. It is well-suited for use in hub and router networking applications.
The available QSOP package reduces discrete resistor count from 18 to a single package resulting in a 75% board
space savings.
