1.3 Description
The LMK03200 family of precision clock conditioners combine the functions of jitter
cleaning/reconditioning, multiplication, and 0-delay distribution of a reference clock. The devices integrate
a Voltage Controlled Oscillator (VCO), a high performance Integer-N Phase Locked Loop (PLL), a partially
integrated loop filter, and up to eight outputs in various LVDS and LVPECL combinations.
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.
