PI6CG338Q AECQ-Grade 2 PCIe® 6.0 Clock Generator Diodes Incorporated PI6CG338Q AECQ-Grade 2 PCIe 6.0 Clock Generator is an 8-output, very low power PCIe® (Gen 1 through Gen 6) clock generator. The PI6CG338Q uses a 25MHz crystal or CMOS reference as an input to generate the 100MHz low-power differential HCSL outputs with on-chip terminations. On-chip terminations save 32x external resistors and make the layout easier. An additional buffered reference output (provided) serves as a low-noise reference for other circuitry.
