Description
The CY292510 is a 3.3V zero delay buffer designed to
distribute high-speed clocks in PC, workstation, datacom,
telecom, and other high-performance applications. It is ideal
for use in SDRAM memory applications, and conforms to the
JEDEC JC40/JC42.5 specification supporting SDRAM DIMM
applications.
The CY292510 has one bank of outputs with output enable
control. Input-to-output skew can be adjusted by varying
load/delay on feedback path. When OE is low, clock outputs
are forced low. V
DDA
can be strapped low to force device into
test mode. See
