LMK03002/LMK03002C  
Precision Clock Conditioner with Integrated VCO  
General Description  
Features  
The LMK03002/LMK03002C precision clock conditioners  
combine the functions of jitter cleaning/reconditioning, multi-  
plication, and distribution of a reference clock. The devices  
integrate a Voltage Controlled Oscillator (VCO), a high per-  
formance Integer-N Phase Locked Loop (PLL), a partially  
integrated loop filter, and four LVPECL clock output distribu-  
tion blocks.  
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)  
The VCO output is optionally accessible on the Fout port. In-  
ternally, the VCO output goes through a VCO Divider to feed  
the various clock distribution blocks.  
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  
Each clock distribution block includes a programmable di-  
vider, 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 ref-  
erence to be distributed to four system components.  
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  
The clock conditioners come in a 48-pin LLP package and are  
footprint compatible with other clocking devices in the same  
family.  
Package: 48 pin LLP (7.0 x 7.0 x 0.8 mm)  
Target Applications  
Data Converter Clocking  
Networking, SONET/SDH, DSLAM  
Wireless Infrastructure  
Medical  
Test and Measurement  
Military / Aerospace
