Features Integrated VCO with very low phase noise floor Integrated Integer-N PLL with outstanding normalized phase noise contribution of -224 dBc/Hz Clock generator performance (10 Hz - 20 MHz) LMK03002C: 200 fs RMS jitter Jitter cleaner performance grade (12 kHz to 20 MHz) LMK03002: 800 fs RMS jitter LMK03002C: 400 fs RMS jitter VCO frequency: 1566 to 1724 MHz Clock output frequency range of 1 to 862 MHz 4 LVPECL clock outputs Partially integrated loop filter Dedicated divider and delay blocks on each clock output Pin compatible family of clocking devices 3.15 to 3.45 V operation Package: 48 pin LLP (7.0 x 7.0 x 0.8 mm) Description The LMK03002/LMK03002C precision clock conditioners combine the functions of jitter cleaning/reconditioning, multiplication, and 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 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 LLP package and are footprint compatible with other clocking devices in the same family.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
