Pericom Semiconductor PI6C49003A
The PI6C49003A is a clock generator device intended for PCIe® Gen2 networking applications. The device includes five 100MHz differential Host Clock Signal Level (HCSL) outputs for PCIe Gen 2, two single-ended 50MHz outputs, one single-ended 32.256MHz output, and one selectable single-ended 33/66/133MHz output. Using a serially programmable SMBUS interface, the PI6C49003A incorporates spread spectrum modulation on the twelve 100MHz HCSL PCIe Gen 2 outputs, and independent frequency margining on the 50MHz output, 33.3333MHz and 66.6666MHz clock outputs.| Part No. | PI6C49003A |
