Lead-free Green PI6CG33401 3.3V Very-Low-Power 4-Output PCIe Clock Generator With On-Chip Termination Features Description
ÎÎ3.3V Supply Voltage The PI6CG33401 is a 4-output very-low-power PCIe Gen1/Gen2/ ÎÎCrystal/CMOS Input: 25MHz Gen3/Gen4/Gen 5 clock generator. It uses 25MHz crystal or CMOS ÎÎFour Differential Low Power HCSL Outputs with On-Chip reference as an input to generate the 100MHz low-power differ- Termination ential HCSL outputs with on-chip terminations. The on-chip ter- ÎÎDefault ZOUT = 100Ω mination can save 16 external resistors and make layout easier. ÎÎIndividual Output Enable An additional buffered reference output is provided to serve as a ÎÎReference CMOS Output low-noise reference for other circuitry. ÎÎProgrammable 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- ÎÎDifferential Outputs Blocked until PLL is Locked ments. It also provides various options such as different slew rate ÎÎSelectable 0%, -0.25%, or -0.5% Spread on Differential and amplitude through SMBUS, so users can configure the de- Outputs vice easily to get the optimized performance for their individual ÎÎStrapping pins or SMBus for Configuration boards. The device also supports selectable spread-spectrum ÎÎDifferential Output-To-Output Skew <50ps options to reduce EMI for various applications.
