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.

Features

• 32 bidirectional CMOS T switches in an 8×4 non-blocking array

• Break-before-make switching configuration

• Fast setup & hold times for switch programming

• 3dB bandwidth of 200MHz

• Low feedthrough and crosstalk, better than -80dB at 5MHz

• Very low differential gain and phase errors

• 12Vpp bipolar signal capability

• On-state resistance 75Ω (max) for VDD=+5V, VEE=-7V

• Switch control through 2-stage latches

• Orthogonal Xi and Yi pin connections for optimized PCB layout

• Latch readback capability for monitoring

Applications

• High-end video routing and switching
