SN65EPT21: SN65EPT21 Temperature Compensation

Part Number: SN65EPT21

Tool/software:

Hi,

The SN65EPT21 (PECL/LVDS differential in TTL out) says its temperature compensated.

Does anyone have any data on the Temperature Coefficient of propagation delay of this part?

Can this part handle ultra low duty cycles like for PPS applications (pulse per second)?

The "Duty Cycle Skew" specification suggests in the Note it is between outputs. The part however only has one output. Does this mean this is a Part-To-Part specification?

Thanks!

Hi Nathan,

Thank you for your questions. This device is very old and we do not have any further information to share on the temperature compensation comment in the datasheet.

You are correct in your understanding of duty cycle skew. It is described well here in this application note (page 3): Defining Skew,Propagation-Delay,Phase Offset (Phase Error)

In this case, since this is a single channel device, the relation is shown in Figure 3.

The device must meet the datasheet specifications, please refer to this application note: Keep an eye on the LVDS input levels (ti.com)

Regards, Amy
