Lead-free Green PI6CG33402C 3.3V Very-Low Power 4-Output PCIe Clock Generator With On-chip Termination Features Description
Î Î 3.3V Supply Voltage The PI6CG33402C is a four-output very-low power PCIe Gen1/Gen2/ Î Î Crystal/CMOS Input: 25MHz Gen3/ Gen4/ Gen5 clock generator. It uses 25MHz crystal or CMOS Î Î Four Differential Low-Power HCSL Outputs with On-chip Termination reference as an input to generate the 100MHz low-power differ- ential HCSL outputs with on-chip terminations. The on-chip ter- Î Î Default ZOUT = 85Ω mination can save 16 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 jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 require- Î Î Differential Outputs Blocked until PLL is Locked ments. It also provides various options such as different slew rate Î Î Selectable 0%, -0.25%, or -0.5% Spread on Differential Outputs 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. The device also supports selectable spread-spectrum Î Î Very-Low Jitter Outputs options to reduce EMI for various applications. à Differential Cycle-to-Cycle Jitter <50ps à PCIe Gen1/Gen2/Gen3/Gen4/Gen5 Compliant
