... Ten (CY2509) or eleven (CY2510) LVCMOS/LVTTL outputs • typical peak cycle-to-cycle jitter • Single output enable pin for CY2510 version, dual pins on CY2509 devices allow shutting down a portion of the outputs • 3.3V power supply • On board 25Ω damping resistors • Available in 24-pin TSSOP package • ...

... GND (LOW, 0) outputs Q5:8 are disabled to a LOW state. enough to meet all the requirements of the memory and logic on the DIMM. The CY2509/10 takes in the signal from the motherboard and buffers out clock signals with enough drive to support all the DIMM board clocking needs. The CY2509/10 is also designed to meet the needs of new PC133 SDRAM designs, operating to 133 MHz ...

... Reference clock provided to the ZDB goes HIGH. Synchronizing the other outputs of the ZDB to the outputs form the ASIC/Buffer is more complex however, as any propagation delay in the ASIC/Buffer must be accounted for.
