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.
