LOW POWER NETWORKING CLOCK GENERATOR

The PI6C49016 is a clock generator device intended for PCIExpress/networking applications. The device includes three 100 MHz differential outputs for PCI-Express using reduced power, one single-ended 125 MHz output, one single-ended 66.66 MHz, and one single-ended 80 MHz output with spread spectrum. Using a serially programmable SMBus interface, the PI6C49016 incorporates spread spectrum modulation on the four 100 MHz PCI-Express outputs with -0.5% down spread and the 80 MHz output with selectable down spread. 25 MHz crystal or clock input Three differential 100 MHz PCI-Express clock outputs – push-pull termination Spread spectrum capability on all 100 MHz PCI-e clock outputs with -0.5% down spread One single-ended 66.66 MHz output One single-ended 125 MHz output for Gigabit Ethernet at 2.5V One single-ended 80 MHz output with selectable down spread 40-pin QFN package Operating voltage 3.3 V ±5% Industrial temperature (-40 to +85°C)
