Description

The UTC008 is a JTAG Switch Module for interface to all slots via one module for prototyping/debugging and software updates.  The power comes from the management (+3.3 V) or the payload (+12 V) depending on the chassis configuration. The UTC008 consumes less than 55 mW. The front connector is standard 0.1 header which mates to most JTAG modules. There are three arbitrated master ports (2 MCH and the front/rear connector). The secondary ports are auto detected if they are present. The modules provides transparent communication between the master and a selected secondary port. All configuration modes uses IEEE1149.1 TAP controller. The JTAG can operate with up to 50 MHz clock.
