Si53212/Si53208/Si53204 Data Sheet

12/8/4-Output PCI-Express Low Jitter, Low Power Gen 1/2/3/4

SRIS Clock Buffer

The Si53212, Si53208, and Si53204 are the industry’s highest performance, low additive

jitter, low power PCIe clock fanout buffer family that can source 12, 8, or 4 100 MHz

PCIe clock outputs. All differential clock outputs are compliant to PCIe Gen1/2/3/4 com-

mon clock and separate reference clock specifications. This family of buffers is spread

spectrum tolerant to pass through a spread input clock. Each device has an individual

hardware output enable control pin for enabling and disabling each differential output.

Other than 100 MHz, the device can also support input frequencies from 10 MHz to 200

MHz. All the devices are packaged in small QFN packages. The small footprint and low-

power consumption make this family of PCIe clock fanout buffers ideal for industrial and

consumer applications. To confirm PCI-Express compliance, the Silicon Labs PCIe

Clock Jitter Tool makes measuring PCIe clock jitter quick and easy. Download it for free
