Description

The 8V54816A is a 16-port, bi-directional cross-point clock switch

designed for clock distribution in MicroTCA.4 systems. It features

16 bi-directional 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:

100, 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 I2

C. At startup, a default configuration is set where all

ports are in High-Impedance mode with outputs disabled.
