Description

The 840001I-25 is a general-purpose clock generator. The 840001I-25 can accept frequency from a 22.4MHz to 170MHz and generate a 22.4MHz to 170MHz output. The 840001I-25 has excellent phase jitter performance, from 637kHz – 10MHz integration range. The 840001I-25 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
