Diodes Incorporated PI6CG33x Gen 4/5 Compliant Clock Generators
Diodes Incorporated PI6CG33x Gen 4/5 Compliant Clock Generators offer an ideal clock solution for data centers, servers, storage, and network applications using the PCIe interface. The PI6CG33x Clock Generator series includes 2-output, 4-output, 6-output, and 8-output devices. These devices use either a 25MHz crystal or a CMOS reference as an input to generate the 100MHz low-power differential High-Speed Current Steering Logic (HCSL) outputs with on-chip terminations. The on-chip termination eliminates the need for external resistors, simplifies PCB layout, and reduces the cost of materials (BOM). An additional buffered reference output is provided as a low-noise reference for other circuitry.
The PI6CG33x Clock Generators use a proprietary PLL design to achieve very low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirements. These devices also support Ethernet applications with 50MHz, 125MHz, and 133.33MHz via SMBus. Offering a programmable slew rate and output amplitude for each output, the PI6CG33x Clock Generators provide flexibility for ease of board design and optimal performance. These devices also support selectable spread-spectrum options to reduce EMI for various applications.
The PI6CG33x Clock Generators are in compact, Pb-free, and RoHS-compliant Thin Quad Flat No-Lead (TQFN) packages.
