cy29773 Summary of contents
Page 1
... The CY29773 is a low-voltage high-performance 200-MHz PLL-based zero delay buffer designed for high-speed clock distribution applications. The CY29773 features one LVPECL and two LVCMOS reference clock inputs and provides 12 outputs partitioned in three banks of four outputs each. Each bank divides the VCO output per SEL(A:C) settings (see Table 2 ...

... SYNC Output In situations where output frequency relationships are not integer multiples of each other the SYNC output provides a signal for system synchronization. The CY29773 monitors the relationship between the QA and the QC output clocks. It provides a low going pulse, one period in duration, one period prior to the coincident rising edges of the QA and QC outputs ...

... QA QC SYNC Power Management The individual output enable/freeze control of the CY29773 allows the user to implement unique power management schemes into the design. The outputs are stopped in the logic ‘0’ state when the freeze control bits are activated. The serial input register contains one programmable freeze enable bit for 12 of the 14 output clocks ...
