Description

The CDCU877 is a high-performance, low-jitter, low-skew, zero-delay buffer that distributes a differential clock inputpair (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.
