The CY23FS08 is a FailSafeZero Delay Buffer with two  
reference clock inputs and eight phase-aligned outputs. The  
device provides an optimum solution for applications where  
continuous operation is required in the event of a primary clock  
failure.  
Continuous, glitch-free operation is achieved by using a  
DCXO, which serves as a redundant clock source in the event  
of a reference clock failure by maintaining the last frequency  
and phase information of the reference clock.  
The unique feature of the CY23FS08 is that the DCXO is in  
fact the primary clocking source, which is synchronized  
(phase-aligned) to the external reference clock. When this  
external clock is restored, the DCXO automatically resynchro-  
nizes to the external clock.  
The frequency of the crystal, which will be connected to the  
DCXO must be chosen to be an integer factor of the frequency  
of the reference clock. This factor is set by four select lines:  
S[4:1]. please see Table 1. The CY23FS08 has three split  
power supplies; one for core, another for Bank A outputs and  
the third for Bank B outputs. Each output power supply, except  
VDDC can be connected to either 2.5V or 3.3V. VDDC is the  
power supply pin for internal circuits and must be connected  
to 3.3V.
