PI6C49003 Networking Clock Generator Features • 3.3V +/-10% Supply Voltage • Uses 25MHz xtal such as Saronix-eCera™ SRX7278 • Five PCIe® 100MHz outputs with optional -0.5% spread spectrum support • Two LVCMOS 50MHz outputs that support +/- 10% frequency margining • One frequency selectable 33/66/133MHz LVCMOS output • One 32.256MHz LVCMOS output • Industrial temperature -40°C to 85°C • Package: 48-pin TSSOP package Description The PI6C49003 is a clock generator device intended for PCIe®/ networking applications. The device includes ﬁve 100MHz differential Host Clock Signal Level (HCSL) outputs for PCIe, two single-ended 50 MHz outputs, one single-ended 32.256MHz output, and one selectable single-ended 33/66/133 MHz output. Using a serially programmable SMBUS interface, the PI6C49003 incorporates spread spectrum modulation on the ﬁve 100 MHz HCSL PCIe outputs, and independent frequency margining on the 50MHz output, 33.3333MHz and 66.6666MHz clock outputs.
