PLL-based zero delay buffer for clock distribution
The Cypress CY2V9950AC is a PLL-based zero delay buffer designed to align output clock edges with the input reference, minimizing skew across a clock tree. It accepts LVCMOS or LVTTL inputs and drives up to eight LVTTL outputs at frequencies up to 200 MHz.
200 MHz maximum frequency and 2:8 fanout
The 200 MHz maximum frequency covers common clock rates for Ethernet PHYs, FPGAs, and memory interfaces. The 2:8 input-to-output ratio lets you distribute one reference clock to eight loads without adding an external fanout buffer. Because the PLL locks to the input, output-to-output skew stays low, which simplifies timing closure on multi-load buses.
Dual supply range and commercial temperature grade
Active lifecycle and RoHS status
However, it is listed as RoHS non-compliant, so designs requiring lead-free assembly will need a RoHS-compliant variant or an alternate part. The 32-TQFP package is surface-mount and widely available through independent distribution.
