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 cloc...
