Not all obsolete parts will have a direct replacement. However, we recommended that you contact your regional sales office.

What are the types of jitter?

There are several types of jitter, but the main ones are: cycle-to-cycle jitter, period jitter, half period jitter, and peak-to-peak jitter. Jitter terminology can be found in AB36: Jitter Measurement Techniques at Application Brief No. 36 or Application Note No. 27.

What are the types of reset output?

There are two types of reset output: push-pull and open-drain as different applications require. If you choose open-drain reset output, pull-up resistor should be added in application circuit. For detailed information, please refer to datasheets or application notes.

What is the lead finish for Pericom products? What about lead-free?
