Description
The DIODES PI6CG332Q is a 2-output very low power PCIe®
Gen 1/Gen 2/Gen 3/Gen 4/Gen 5/Gen 6 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 8 external resistors
and make layout easier. An additional buffered reference output
is provided to serve as a low noise reference for other circuitry.
It uses Diodes' proprietary PLL design to achieve very low
jitter that meets PCIe Gen 1/Gen 2/Gen 3/Gen 4/Gen 5/Gen 6
requirements. It also provides various options such as different slew rate and amplitude through SMBUS so that users can
configure the device easily to get the optimized performance
for their individual boards. The device also supports selectable
spread-spectrum options to reduce EMI for various applications.
