Propagation Delay Time For The CY2309

Last Updated: November 23, 2011

What is the propagation delay time for the CY2309?


The CY2309 with PLL enabled has very little propagation delay if all outputs are loaded evenly. The datasheet spec reads t6a < +/-350 ps. In bypass mode, the CY2309 bypasses the PLL and therefore acts as a normal buffer, with propagation delay (t6b) in the datasheet as
Min = 1 ns,
Typ = 5 ns,
Max = 8.7 ns.

With the PLL enabled, the part acts as a "zero delay buffer." In this mode, the PLL reduces the propagation delay from input to output compared to the bypass mode.
