Part Number: SN65LV1224B
Other Parts Discussed in Thread: SN65LV1023A

Hi team,

Could you please let me know the difference between SN65LV1224-SN65LV1224 and DS92LV1021-DS92LV1212?

Does SN65LV1224 has timing difference from DS92LV1212?

Does SN65LV1023 behaves differently from DS92LV1021 when inputting High on SYNC1 pin?

Regards,

Itoh

Hi Itoh-san,

You can reference this application note for the differences:

http://www.ti.com/lit/an/slla435/slla435.pdf

You can also read the SN65LV1023a datasheet for a description of SYNC1 and how it behaves.

Regards,

I.K.

Hi IK-san,

Could you please tell me if SN65LV1023 behaves differently from DS92LV1021 when High is input to SYNC1 pin?

I could not find it from SN65LV1023a datasheet.

Hi Itoh-san,

Comparing datasheets the behavior looks to be similar between devices.

Hi IK-san,

One more question from my customer.

Will 10ns jitter at REFCLK 32.768MHz cause unlock the PLL?

Itoh-san,

10ns is too much. The jitter tolerance for the REFCLK should be similar to the TCLK: less than 150ps.
