Lead-free Green PI6CG33802C 3.3V Very Low Power 8-Output PCIe Clock Generator With On-Chip Termination Features Description
Î Î 3.3V Supply Voltage The PI6CG33802C is an 8-output, very-low-power PCIe Gen1/ Î Î Crystal/CMOS Input: 25 MHz Gen2/Gen3/Gen4/Gen5 clock generator. It uses a 25MHz crystal or CMOS reference as an input to generate the 100MHz low-power Î Î Eight Differential Low-Power HCSL Outputs with On-Chip Termination differential HCSL outputs with on-chip terminations. The on-chip termination can save 32 external resistors and make layout easier. Î Î Default ZOUT = 85Ω An additional buffered reference output is provided to serve as a Î Î Individual Output Enable low-noise reference for other circuitry. Î Î Reference CMOS Output Î Î Programmable Slew Rate and Output Amplitude for Each It uses Diodes' proprietary PLL design to achieve very-low Output jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 require- ments. It also provides various options, such as different slew Î Î Differential Outputs Blocked Until PLL is Locked rate and amplitude through SMBUS, so users can easily con- Î Î Selectable 0%, -0.25%, or -0.5% Spread on Differential Outputs figure the device to get the optimized performance for their individual boards. The device also supports selectable spread- Î Î Strapping Pins or SMBus for Configuration spectrum options to reduce EMI for various applications.
