Part Number | CDCV855I |
Manufacturer | Texas Instruments |
Title | 2.5-V PHASE-LOCK LOOP CLOCK DRIVER |
Description | The CDCV855 is a high-performance, low-skew, low-jitter zero delay buffer that distributes a differential clock input pair (CLK, CLK) to four dif... |
Features |
erential clock input pair (CLK, CLK) to four differential pairs of clock outputs (Y[0:3], Y[0:3]) and one differential pair of feedback clock outputs (FBOUT, FBOUT). When PWRDWN is high, the outputs switch in phase and frequency with CLK. When PWRDWN is low, all outputs are disabled to a high-impeda... |
