A product Line of bP Diodes Incorporated Lead-free GreenPI6CG33202C3.3V Very Low Power 2-Output PCIe Clock Generator With On-chip TerminationFeaturesDescription Î Î 3.3V Supply Voltage The PI6CG33202C is a 2-output very low power PCIe Gen1/Gen2/ Î Î Crystal/CMOS input: 25 MHz Gen3/Gen4/Gen5 clock generator. It uses 25MHz crystal or CMOS Î Î 2 Differential low power HCSL outputs with on-chip termination reference as an input to generate the 100MHz low power dif- ferential HCSL outputs with on-chip terminations. The on-chip Î Î Default ZOUT = 85Ω termination can save 8 external resistors and make layout easier. Î Î Individual output enable An additional buffered reference output is provided to serve as a Î Î Reference CMOS output low noise reference for other circuitry. Î Î Programmable slew rate and output amplitude for each output It uses Diodes' proprietary PLL design to achieve very low Î Î Differential outputs blocked until PLL is locked jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 require- Î Î Selectable 0%, -0.25% or -0.5% spread on differential outputs ments. It also provides various options such as different slew rate Î Î Strapping pins or SMBus for configuration and amplitude through SMBUS so that users can configure the Î Î Differential Output-To-Output Skew <50ps device easily to get the optimized performance for their individ- Î Î Very-Low Jitter Outputs ual boards. The device also supports selectable spread-spectrum à Differential Cycle-To-Cycle Jitter <50ps options to reduce EMI for various applications. à PCIe Gen1/Gen2/Gen3/Gen4/Gen5 Compliant à CMOS REFOUT Phase Jitter Block Diagram • < 0.3ps RMS, SSC off • <1.5ps RMS, SSC on REFOUT Î Î Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) OE[1:0]# Î Î Halogen and Antimony Free. “Green” Device (Note 3) Î Î For automotive applications requiring specific change control Q1 (i.e. parts qualified to AEC-Q100/101/200, PPAP capable, XTAL_IN/CLK OSC PLL XTAL_OUT SS and manufactured in IATF 16949 certified facilities), please Q0 contact us or your local Diodes representative.
