Pb A product Line of Diodes Incorporated Lead-free Green PI6CG188Q 8-Output PCIe Gen 4 Clock Generator for Automotive Applications Features Description ÎÎ1.8V Supply Voltage The PI6CG188Q is an 8-output very-low-power PCIe Gen1/Gen2/ Gen3/Gen4 clock generator. It uses 25MHz crystal or CMOS reference as an input to generate the 100MHz low-power differential HCSL outputs with on-chip terminations. The on-chip termination can save 32 external resistors and make layout easier. An additional buffered reference output is provided to serve as a low-noise reference for other circuitry. ÎÎCrystal/CMOS Input: 25MHz ÎÎ8 Differential Low-Power HCSL Outputs with On-Chip Termination ÎÎIndividual Output Enable ÎÎReference CMOS Output ÎÎProgrammable Output Slew Rate and Output Amplitude for Each The device uses Diodes' proprietary PLL design to achieve verylow jitter that meets PCIe Gen1/Gen2/Gen3/Gen4 requirements. It also provides various options, such as different slew rate and amplitude, through strapping pins or SMBUS, so users can configure the device easily for optimized performance for their individual boards. The device also supports selectable spreadspectrum options to reduce EMI for Automotive applications. ÎÎDifferential Outputs Blocked until PLL is Locked ÎÎSelectable 0%, -0.25%, or -0.5% Spread on Differential Outputs ÎÎStrapping pins or SMBus for Configuration ÎÎ3.3V Tolerant SMBus Interface Support ÎÎVery-Low-Jitter Outputs àà Differential Cycle-to-Cycle Jitter
