A product Line of bP Diodes Incorporated Lead-free GreenPI6CB33802Very-Low-Power 8-Output PCIe Clock Buffer with On-Chip TerminationFeaturesDescription Î Î 3.3V Supply Voltage The PI6CB33802 is an eight-output very-low-power PCIe PCIe Î Î HCSL Input: 100MHz, also supports 50MHz, 125MHz, or Gen1/Gen2/Gen3/Gen4/Gen5 clock buffer. It takes a reference 133.33MHz via SMBus input to fanout eight 100MHz low-power differential HCSL out- Î Î Eight Differential Low-Power HCSL Outputs with On-Chip puts with on-chip terminations. The on-chip termination can Termination save 32 external resistors and make layout easier. An individual Î Î Default ZOUT = 85Ω OE pin for each output provides easier power management. Î Î Spread Spectrum Tolerant It uses Diodes proprietary PLL design to achieve very-low jitter Î Î Individual Output Enable that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirements. Î Î Programmable Slew Rate and Output Amplitude for Each Other than PCIe 100MHz support, this device also supports Output Ethernet application with 50MHz, 125MHz, and 133.33MHz via Î Î Differential Outputs Blocked until PLL is Locked SMBus. It provides various options, such as different slew rate and amplitude, through SMBUS, so users can configure the de- Î Î Strapping Pins or SMBus for Configuration vice easily to get the optimized performance for their individual Î Î Differential output-to-output skew <50ps boards. Î Î Very low jitter outputs Î Differential cycle-to-cycle jitter <50ps Block Diagram Î PCIe Gen1/Gen2/Gen3/Gen4/Gen5 CC compliant OE[7:0]# Î PCIe Gen 2 and 3 SRiS and SRnS compliant Q7 Î Î Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Q6 Î Î Halogen and Antimony Free. “Green” Device (Note 3) IN+ PLL IN- Î Î For automotive applications requiring specific change control Q5 (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, and manufactured in IATF 16949 certified facilities), please Q4 contact us or your local Diodes representative.
