The 844251-15 is an Ethernet Clock Generator and a member of the HiPerClocks™ family of high-performance devices. The 844251-15 uses an 18pF parallel resonant crystal over the range of 23.2MHz - 30MHz. For Ethernet applications, a 25MHz crystal is used. The device has excellent <1ps phase jitter performance, over the 1.875MHz - 20MHz integration range. The 844251-15 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
