DESCRIPTION  
The CDCU877 is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock  
input pair (CK, CK) to ten differential pairs of clock outputs (Yn, Yn) and to one differential pair of feedback clock  
outputs (FBOUT, FBOUT). The clock outputs are controlled by the input clocks (CK, CK), the feedback clocks  
(FBIN, FBIN), the LVCMOS control pins (OE, OS), and the analog power input (AVDD). When OE is low, the  
clock outputs, except FBOUT/FBOUT, are disabled while the internal PLL continues to maintain its locked-in  
frequency. OS (output select) is a program pin that must be tied to GND or VDD. When OS is high, OE functions  
as previously described. When OS and OE are both low, OE has no affect on Y7/Y7, they are free running.  
When AVDD is grounded, the PLL is turned off and bypassed for test purposes.  
When both clock inputs (CK, CK) are logic low, the device enters in a low power mode. An input logic detection  
circuit on the differential inputs, independent from input buffers, detects the logic low level and performs in a low  
power state where all outputs, the feedback, and the PLL are off. When the clock inputs transition from being  
logic low to being differential signals, the PLL turns back on, the inputs and the outputs are enabled, and the  
PLL obtains phase lock between the feedback clock pair (FBIN, FBIN) and the clock input pair (CK, CK) within  
the specified stabilization time.  
The CDCU877 is able to track spread spectrum clocking (SSC) for reduced EMI. This device operates from  
—40°C to 85°C.
