Description
The ICS840021 is a Gigabit Ethernet Clock Generator and a member of the HiPerClocksTM family of high performance devices from IDT. The ICS840021 uses a 25MHz crystal to synthesize 125MHz. The ICS840021 has excellent phase jitter performance, over the 1.875MHz 20MHz integration range. The ICS840021 is packaged in a small 8-pin TSSOP, making it ideal for use in systems with limited board space.
