CLOCK AND OSCILLATOR SELECTOR / 13
PCI Express Clock Buffers (PCIe)
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.
