DIODES Incorporated Application Specific Clock/Timing PI6C20400ALEX

The PI6C20400ALEX is a PCIe® 2.0 compliant high-speed, low-noise differential clock buffer designed to distribute the differential SRC clock from the PI6C410BS to four differential pairs of clock outputs. It features a low skew of less than 50 ps and low jitter of less than 50 ps cycle-to-cycle, with an additive RMS phase jitter of less than 1 ps. The device supports both PLL and bypass modes, operating at 100 MHz in PLL mode and 100 to 400 MHz in bypass mode. Control of the clock outputs is managed through input selection pins, including SRC_STOP#, PWRDWN#, and SMBus signals. When either SRC_STOP# or PWRDWN# is low, the outputs are tri-stated. The device operates at a supply voltage of 3.3V and is fully RoHS compliant, making it suitable for environmentally conscious applications. The PI6C20400ALEX is available in a 28-pin TSSOP package, providing a compact solution for timing applications in PCIe® chipsets.
