MT88V32中文资料MITEL数据手册PDF规格书

描述 Description

The MT88V32 is a digitally programmable (TTL levels) 8×4 crosspoint switch that is designed to control wideband analog (video) signal.

Each of the 32 nodes of the switching matrix has a Tswitch, see Fig.1. This grounds the nodes of all open connections, which greatly reduces feedthrough noise. In order to reduce crosstalk, individual analog signal lines are isolated by interleaving them with ground lines.
