The device selects between two independent reference inputs to a phase-locked loop and generates up to four different frequencies on configurable differential output channels and also a copy of the reference clock on a LVCMOS output channel. Each of the four output channels has a configurable integer divider. Together with the output muxes, this allows up to five different frequencies. Clock distribution dividers are reset in a deterministic way for clean clock gating and glitch-less update capability. Flexible power-down options allow to optimize the device for lowest power consumption in active and standby operation. Typically four 156.25MHz LVDS outputs consume 150m W at...
