General Description

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.

Each clock distribution block includes a programmable divider, a phase synchronization circuit, a programmable delay, a clock output mux, and an LVDS or LVPECL output buffer.

Key Features

  • 1 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.
  • 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 WQFN (7.0 x 7.0 x 0.8 mm) 3.
