LMK00105: Alternative devices to Renesas 23S05T-1DCGI and 670M-01LF

Part Number: LMK00105
Other Parts Discussed in Thread: LMK1C1104, CDCVF2505, CDCLVC1104, CDCE6214

Hi Team,

Our customer is looking for alternative devices to Renesas 23S05T-1DCGI and 670M-01LF. I found the LMK00105 from our list of clock buffers. Can you please advise if can be use as alternative to 23S05T-1DCGI.

It seems that we don't have a similar device to 670M-01LF, can you please confirm.

  • Hi Danilo,

    23S05T-1DCGI  is a zero delay buffer. Do you need zero delay option for this device. If so I would recommend CDCVF2505 or CDCE6214 which is similar and functional compatible to this part. If zero delay is not a requirement then you can use CDCLVC1104 or LMK1C1104 buffers for simple fanout.

    For the second device, we can recommend CDC6214 which is a close functional compatible device. But it doesn't have pin options to do multiplication.

    Let me know if you have any further questions?
