Texas Instruments' low-add-on jitter, low-propagation delay clock buffer is designed to meet stringent performance requirements

     The CDCDB400 from Texas Instruments is a four-output LP-HCSL, DB800ZL compliant clock buffer with low attached jitter and low propagation latency. The buffer is designed to meet the stringent performance requirements of PCIe Gen 1 to Gen 6, QuickPath Interconnect (QPI), UPI, SAS, and SATA interfaces in CC, SRNS, or SRIS architectures.

     The CDCDB400 allows buffering and copying of a single clock source, supporting up to four separate outputs in LP-HCSL format. The device also includes status and control registers accessible through the SMBus 2.0 compatible interface.

     The clock buffer integrates external passive components to reduce the overall system cost. The CDCDB400 meets or exceeds the system parameters in the DB800ZL and DB2000Q specifications. The device comes in a 5 mm x 5 mm, 32 pin VQFN package.
