LMK1C1102: Request for selection of LVCMOS Clock buffer

Part Number: LMK1C1102

Tool/software:

Please consider my request and provide recommendations for a clock buffer that meets the following criteria:

Frequency Support: 52 MHz or higher
Voltage Compatibility: LVCMOS 1.2V for both input and output, with 3.3V tolerance if possible
Zero Delay: Must provide zero delay functionality
Phase Jitter: Should exhibit low additive phase jitter, preferably less than 250 fs

Your assistance in finding a suitable clock buffer that satisfies these requirements would be greatly appreciated.

Hello Krishna,
Most of our buffer operate either 1.8V, 2.5, & 3.3V.
How many outputs do you require?

Regards,

Vicente

One more thing Krishna,
Most of our buffer don't offer a zero delay mode.

There will be a prop delay. The outputs will be phase aligned but even then there will be some output-to-output skew.
The delay
Zero delay mode requires a PLL since there is a feedback mechanism implemented.

Vicente

Hi Krishna,

LMK1C1102 works but it only has two outputs. If you require more we have higher output variants.
