The devices integrate a Voltage Controlled Oscillator (VCO), a high performance Integer-N Phase Locked Loop (PLL), a partially integrated loop filter, and four LVPECL clock output distribution blocks.
The VCO output is optionally accessible on the Fout port.
Internally, the VCO output goes through a VCO Divider to feed the various clock distribution blocks.
Each clock distribution block includes a programmable divider, a phase synchronization circuit, a programmable delay, a clock output mux, and an LVPECL output buffer.
This allows multiple integer-related and phase-adjusted copies of the reference to be distributed to four system components.
The clock conditioners come in a 48-pin WQFN package and are footprint compatible with other clocking devices in the same family.
