LMK04828: Clock for THS5641A

Andrew Baek

Part Number: LMK04828
Other Parts Discussed in Thread: THS5641A

We are using LMK04828 to provide a clock for THS5641A.

LMK04828 doesn't seem to generate a 3.3V CMOS clock output, which I believe THS5641A is expecting.

I've summarized the issue in the attached pdf.

Could you suggest an output type and RC values to meet the digital input spec of THS5641A?

Thank you,

Hi Andrew,

LMK04828 does not support LVCMOS output at DCLKout and SDCLKout. All available output formats do not meet THS input specification.

LVCMOS output is supported only at OSCout.

Hi Noel,

Just a follow-up.

We used a 3.3V clock from FPGA and got THS5641A working.

Thank you,

Andrew
