The CDCDB2000 is a 20-output LP-HCSL, DB2000QL compliant, clock buffer capable of distributing the reference clock for PCIe Gen 1-7, QuickPath Interconnect (QPI), UPI, SAS, and SATA interfaces. The SMBus, SBI, and 8 output enable pins allow the configuration and control of all 20 outputs individually. The CDCDB2000 is a DB2000QL derivative buffer and meets or exceeds the system parameters in the DB2000QL specification. The CDCDB2000 is packaged in a 6mm × 6mm TLGA/GQFN package with 80 leads.
