9ZX21901D Clock Buffers

Renesas Electronics 9ZX21901D Clock Buffers are the second-generation DB1900Z differential buffer for Intel Purley and newer platforms. These clock buffers are backward compatible with the 9ZX21901C clock buffer while offering much-improved phase jitter performance. The 9ZX21901D clock buffers can provide outputs up to 400MHz in bypass mode. These buffers feature fixed feedback paths, spread spectrum compatibility, and an SMBus interface. Typical applications include servers, storage, and networking.
