Diodes' PI6CG18xxx is a family of very low power PCIe Gen4 multi-output (2/4/8) clock generators. They use a 25 MHz crystal or CMOS reference as an input to generate multiple 100 MHz low power HCSL outputs with on-chip terminations. The on-chip terminations save four external resistors/output and make layout easier. An additional buffered reference output is provided to serve as a low noise reference for other ICs in the circuitry. The PI6CG15xxx is the 1.5 V version of the PI6CG18xxx clock generator series. The PI6CB18xxx is a family of very low power PCIe Gen4 clock buffers with 2/4/6/8 outputs. These buffers include on-chip termination and individual output enables for improved power management.
