PI6CG18401ZHIE

A product Line of Diodes Incorporated PI6CG18401 Very Low Power 4-Output PCIe Clock Generator With On-chip Termination Features Description ÎÎ1.8V supply voltage The PI6CG18401 is an 4-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 16 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: 25 MHz ÎÎ4 differential low power HCSL outputs with on-chip termination ÎÎIndividual output enable ÎÎReference CMOS output ÎÎProgrammable Slew rate and output amplitute for each output It uses Diodes proprietary PLL design to achieve very low jitter that meets PCIe Gen1/Gen2/Gen3 requirements. It also provides various options such as different slew rate and amplitude through strapping pins or SMBUS so that users can configure the device easily to get the optimized performance for their individual boards. The device also supports selectable spreadspectrum options to reduce EMI for various 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 ÎÎ Differential cycle-to-cycle jitter
