LMK03328: CLOCK JITTER CLEANER

Part Number: LMK03328

We want to output a 74.25MHz input using a jitter cleaner. Both the input and output are 74.25MHz.

Is the LMK03328 suitable for a single channel?

Or is there another IC?

Hi Kim,

You can use a clock buffer for this use case. Refer to this link on all the buffer offerings.

I'm currently working on a system-on-chip (SOC) and would like to reduce jitter in the PCLK signal going into the SDI input.

This is my first time using a clock buffer, so please recommend an IC that fits this use case.

Kim

Hi Kim,

Depending on how noisy your reference clock and jitter you are trying to achieve, below are the options you can research based on your use case.

1- CDCE6214 - 4 output channel

2- LMK5B12204 - 4 output channel

3- LMK03318 - 8 output channel

Additionally, you can also reference the jitter cleaner page more devices.

Best,

Sandra
