A Product Line of Pb Diodes Incorporated Lead-free Green PI6CB332001 20-Output PCIe Gen4/Gen5 Clock Buffer With On-chip Termination Features Description e PTh I6CB332001 is a 20-output very low power PCIe Gen1/ Supports Intel s DB2000QL spec Gen2/Gen3/Gen4/Gen5 clock buffer. It is capable of distributing 3.3V supply voltage the reference clocks for UPI, SAS, SATA, and other applications HCSL input: 100MHz (typ), up to 400MHz as well. It takes an reference input to fanout twenty 100MHz low 20 differential low power HCSL outputs with on-chip power differential HCSL outputs with on-chip terminations. The termination on-chip termination can save 80 external resistors and make lay- out easier. OE pins combined with SMBus bits as well as 3-wire Two output enable control modes side band interface provide easier power management for each yTraditional 8 OE pins and 20 SMBus bits output. ySimple 3-wire Side-Band interface real-time control It uses Diodes proprietary design to achieve very low jitter that SMBus interface support meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirement.
