Description

The 840031I is an IEEE 1394b Clock Generator and a member of the HiPerClocksTM family of high performance devices from ICS. The 840031I uses a 24.576MHz crystal to synthesize 98.304MHz. The 840031I has excellent phase jitter performance, from 12KHz – 20MHz integration range. The 840031I is packaged in a small 8-pin SOIC, making it ideal for use in systems with limited board space.
