LMK02000  
Precision Clock Conditioner with Integrated PLL  
General Description  
Features  
The LMK02000 precision clock conditioner combines the  
functions of jitter cleaning/reconditioning, multiplication, and  
distribution of a reference clock. The device integrates a high  
performance Integer-N Phase Locked Loop (PLL), three  
LVDS, and five LVPECL clock output distribution blocks.  
20 fs additive jitter  
Integrated Integer-N PLL with outstanding normalized  
phase noise contribution of -224 dBc/Hz  
Clock output frequency range of 1 to 800 MHz  
3 LVDS and 5 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 LVDS or LVPECL output buffer.  
This allows multiple integer-related and phase-adjusted  
copies of the reference to be distributed to eight system com-  
ponents.  
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)  
The clock conditioner comes in a 48-pin LLP package and is  
footprint compatible with other clocking devices in the same  
family.  
Target Applications  
Data Converter Clocking  
Networking, SONET/SDH, DSLAM  
Wireless Infrastructure  
Medical  
Test and Measurement  
Military / Aerospace
