Description

The PI6CB18200 is a 2-output very low power PCIe Gen1/Gen2/Gen3/Gen4 clock buffer. It takes an reference input to fanout two 100MHz low power differential HCSL outputs. Individual OE pin for each output provides easier power management.

It uses Diodes' proprietary PLL design to achieve very low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4 requirements. Other than PCIe 100MHz support, this device also support Ethernet application with 50MHz or 125MHz via SMBus. It 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.

Feature(s)

  • 1.8V supply voltage
  • HCSL input: 100MHz, also support 50MHz or 125MHz via SMBus
  • 2 differential low power HCSL outputs
  • Individual output enable
  • Programmable Slew rate and output amplitude for each output
  • Differential outputs blocked until PLL is locked
  • Strapping pins or SMBus for configuration;
  • 3.3V tolerant SMBus interface support
  • Very low jitter outputs
  • Differential cycle-to-cycle jitter <50ps
  • Differential output-to-output skew <50ps
  • PCIe Gen1/Gen2/Gen3 compliant
  • Packaging (Pb-free & Green): 24-lead 4×4mm TQFN
