DESCRIPTION

· The PI6CG18200 is a 2-output, very low power PCIe Gen1/Gen2/Gen3/Gen4 clock generator.

· It uses a 25MHz crystal or CMOS reference input to generate 100MHz low power differential HCSL outputs with on-chip terminations.

· It includes a buffered reference output for low noise reference in other circuits.

· Features Diodes Incorporated's proprietary PLL design for very low jitter, meeting PCIe Gen1/Gen2/Gen3/Gen4 requirements.

· Offers configurable slew rate and amplitude via strapping pins or SMBUS for optimized performance.

· Supports selectable spread-spectrum options to reduce EMI.

FEATURES

· 1.8V supply voltage.

· Crystal/CMOS input: 25 MHz.

· 2 differential low power HCSL outputs with individual output enable.

· Reference CMOS output.

· Programmable slew rate and output amplitude for each output.

· Differential outputs blocked until PLL is locked.

· Selectable 0%, -0.25%, or -0.5% spread on differential outputs.

· Configurable via strapping pins or SMBus; 3.3V tolerant SMBus interface.

· Very low jitter outputs: differential cycle-to-cycle jitter <50ps, differential output-to-output skew <50ps.

· PCIe Gen1/Gen2/Gen3/Gen4 compliant.

· CMOS REFOUT phase jitter < 1.5ps RMS.

· Packaging: 24-lead 4×4mm TQFN (Pb-free & Green).

APPLICATIONS

· Suitable for PCIe Gen1/Gen2/Gen3/Gen4 compliant systems.

· Ideal for applications requiring low power and low jitter clock generation.

· Useful in systems needing configurable slew rate and amplitude for optimized performance.

· Applicable in environments where EMI reduction through spread-spectrum options is beneficial.
