LMK03000CISQ/NOPB

The LMK03000CISQ/NOPB from Texas Instruments is a precision clock conditioner designed for jitter cleaning, reconditioning, multiplication, and distribution of reference clocks. This device integrates a Voltage Controlled Oscillator (VCO) and a high-performance Integer-N Phase Locked Loop (PLL).

Key electrical specifications include a maximum output frequency of 1570 MHz and a typical RMS jitter of 800 fs. It supports a core and output supply voltage range of 3.15V to 3.45V. The device features 9 LVDS and LVPECL outputs, with input compatibility for LVCMOS, LVDS, and LVPECL signals. It also includes a VCO divider with values from 2 to 8 and channel dividers from 1 to 510.

Packaged in a 48-pin WQFN (7x7 mm) with a surface mount type, the LMK03000CISQ/NOPB operates within an ambient temperature range of -40°C to 85°C. Its integrated VCO provides very low phase noise, and the PLL offers outstanding normalized phase noise contribution. This clock conditioner is suitable for applications requiring precise clock distribution and signal integrity.

The LMK03000 family offers multiple integer-related and phase-adjusted copies of the reference clock to up to eight system components. Each clock distribution block includes programmable dividers, phase synchronization circuits, and programmable delays, along with LVDS or LVPECL output buffers.
