6 / CLOCK A ND OSCILL ATOR SELEC TOR

PCIe CLOCK FEATURES

• Full portfolio of PCI Express (PCIe) Gen 1/2/3 clocks

and buffers

• All products utilize push-pull HCSL output buffers

• Fully integrated termination resistors on

PCIe outputs

• Low power consumption

• Programmable spread spectrum

• Available hardware strapping pin for spread enable

• Also supports LVPECL, LVDS, or CML levels

• Industrial temperature grade

• Individual output enable control

• Small form factor QFN packaging

Silicon Labs offers the lowest power, highest performance PCI-Express clock generators in the market. All devices in the

portfolio feature low power push-pull output buffer technology, providing benefits of low power consumption, reduced

external terminating resistors and smaller packaging. To optimize performance, the devices support programmable drive

strength, rise/fall times and output impedance. Basic HCSL PCIe and high-performance differential clocks and buffers are

available. Support for down spread spectrum clock generation is also provided.
