LMK02002 Precision Clock Conditioner with Integrated PLL www.DataSheet4U.com PRELIMINARY August 2007 LMK02002 Precision Clock Conditioner with Integrated PLL General Description The LMK02002 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), and four LVPECL clock output 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 eight system components. The clock conditioner comes in a 48-pin LLP package and is footprint compatible with other clocking devices in the same family. Features ■ 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 4 LVPECL clock outputs 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) Target Applications ■ ■ ■ ■ ■ ■ Data Converter Clocking Networking, SONET/SDH, DSLAM Wireless Infrastructure Medical Test and Measurement Military / Aerospace Functional Block Diagram 30023301 TRI-STATE® is a registered trademark of Nationa...
