The LMK00804B datasheet says it accepts both single ended and differential inputs.

1) When only using a single ended LVCMOS input, is the output differential?

Hi Pete,

The LMK00804B is a 2:4 LVCMOS buffer. This means that the 2 possible inputs (either single-ended or differential) are buffered to 4 LVCMOS outputs.

1) Using a single-ended or differential input will provide 4 LVCMOS (single-ended) outputs.

Regards,

Jennifer

Thanks Jennifer, that clarifies it. Does TI have a chip that does single ended LVCMOS to differential LVCMOS or CMOS? Ideally in a 1:4 but can be 1:8, 2:4, ETC.

Hi Pete,

you can have a look at the following for differential CMOS outputs. It will require programming.

CDCE6214 (program to buffer mode/turn off PLL), CDCE18005, CDCUN1208LP
