The CDCUN1208LP is a 2:8 fan-out buffer featuring a wide operating supply range, two
universal differential/single-ended inputs, and universal outputs (HCSL, LVDS, or LVCMOS) with
edge-rate control. The clock buffer supports PCIe Gen1, Gen2 and Gen3. One of the device inputs
includes a divider that provides divide values of /1, /2, /4, or /8. The CDCUN1208LP is offered in
a 32-pin QFN package, reducing the solution footprint. The device is flexible and easy to use. The
state of certain pins determines device configuration at power up. Alternately, the CDCUN1208LP
provides a SPI/I2C port with which a host processor controls device
settings. The CDCUN1208LP delivers excellent additive jitter performance, and low power
consumption. The output section includes four dedicated supply pins enabling the operation of
output ports from different power supply domains. This provides the ability to clock devices
switching at different LVCMOS levels without the need for external logic level translation
circuitry.
