Silicon Labs SL28SRC04BZI

Description
The Silicon Labs SL28SRC04 is a low-power PCI Express Gen 2 & Gen 3 clock generator designed for high-performance computing and networking applications. It features four 100-MHz differential SRC clocks with low-power push-pull output buffers, integrated 33-ohm series termination resistors, and low jitter (<50 ps). The SL28SRC04 also supports spread spectrum clocking via an SSON# input and I²C interface with readback capabilities.
