LMK04832-SP: Max SPI Data Rate for LMK04832-SP

Jack Zhang

Part Number: LMK04832-SP

Hello, what is the maximum data rate supported by the LMK04832-SP for the SPI interface and CLKOUTX outputs when implemented as LVDS? Any help appreciated. Thank you.

Hi Jack,

The max. SPI speed is 1/400ns.

I will check with my buddy on the supported LVDS frequency.

Hi Jack,

Apologies for the lengthy delay. Based on my data, it looks like LVDS can usually get up to about 800MHz before the output bandwidth begins to roll off signal amplitude. I would recommend using HSDS output formats above 800MHz, as the HSDS outputs will begin to approach LVDS levels at higher frequencies.

Regards,

Derek Payne
