LMK02000ISQ

The LMK02000ISQ from Texas Instruments is a high-performance precision clock conditioner designed for jitter cleaning, reconditioning, multiplication, and distribution of reference clocks. It integrates a sophisticated Integer-N Phase Locked Loop (PLL) to achieve outstanding normalized phase noise contribution of -224 dBc/Hz and additive jitter as low as 20 fs.

This device provides flexible clock distribution with a clock output frequency range from 1 to 800 MHz. It features three LVDS and five LVPECL clock outputs. Each output block includes a programmable divider, phase synchronization circuit, programmable delay, clock output multiplexer, and an LVDS or LVPECL output buffer. This enables the distribution of multiple integer-related and phase-adjusted copies of the reference clock to various system components.

The LMK02000ISQ operates with a supply voltage range of 3.15 to 3.45 V and is specified for an operating temperature range of -40 to 85 °C. It comes in a compact 48-pin WQFN package with dimensions of 7.0 x 7.0 x 0.8 mm, making it footprint compatible with other clocking devices in the same family. The standard package quantity is 250 units on a small tape and reel.

This clock distributor is suitable for applications requiring precise clock synchronization and jitter reduction, such as telecommunications infrastructure, high-speed data converters, and test and measurement equipment.
