Question One customer would like to transmit the 100Hz clock by isolated RS-485. They need less than 100 ns jitter for this 100Hz clock. I suggest 2 solutions for them. The first one is ADuM2483, the second one is ADuM1201 + RS-485 transceiver (ADM483E for example). Because they insert a lot on the clock jitter after these transmission loops, the jitter caused by the RS-485/Isolater will be very important. But I don't find the spec about the jitter added to this 100Hz clock from any of these two parts datasheets. Would you please suggest which parameter of the iCoupler will effect on the jitter added by ADuM1201? Or can we calculate the jitter by any of the parameters in the datasheet? Answer While jitter is not a specification (as it would be very difficult/expensive to test in production) we have perform characterization measurements in the lab. The jitter we measured is less than 50 ps - much less that the 100 ns that the customer is seeking.

Question Can you get the ADuM1201 in a Mil Spec EP range like the 1200 ? Answer An alternative to ADuM1201 would be ADuM3211TRZ-EP. We are prioritizing the ADUM3210/11 first and expect to release the ADUM340X family the following quarter. The projects have been slightly delayed but we’re hoping to get on track soon. We think the April 2014 time frame will be ok for the ADUM3210/11 and Q3 2014 for the ADUM340X. ADUM3210TRZ-EP ADUM3211TRZ-EP ADUM3400TRWZ-EP ADUM3401TRWZ-EP ADUM3402TRWZ-EP

ADUM1201 suitable to work in CAN Bus?

Question

Could you please confirm this part, ADUM1201WURZ, being suitable to use in CAN
isolation?

Answer

In principal it will work - it is depending on the speed on the CAN Bus and the
length of the CAN Bus. The issue is the propagation-delay-time at the CAN Bus
Arbitration.

You should use our CAN bus Isolators for this type of application
