Overview
Description
The 8V54816A is a 16-port, bidirectional cross-point clock switch designed for clock distribution in MicroTCA.4 systems. It features 16 bidirectional M-LVDS ports. Each port can be individually set as input or output. Each output port can be connected to any port defined as input. Each port features switchable termination (ON: 100Ω, OFF: High impedance). Output ports can drive up to 19-inch PCB tracks with M-LVDS levels. The device is optimized for very low additive phase noise. Configuration of the device is achieved by I²C. At startup, a default configuration is set where all ports are in High-Impedance mode with outputs disabled.
