DESCRIPTION (CONTINUED)  
SuperSyncFIFOsareparticularlyappropriatefornetwork,video,telecom-  
munications,datacommunicationsandotherapplicationsthatneedtobuffer  
largeamountsofdata.  
The input port is controlled by a Write Clock (WCLK) input and a Write  
Enable (WEN) input. Data is written into the FIFO on every rising edge of  
WCLKwhenWENisasserted.TheoutputportiscontrolledbyaReadClock  
(RCLK) input and Read Enable (REN) input. Data is read from the FIFO on  
every rising edge of RCLK when REN is asserted. An Output Enable (OE)  
input is provided for three-state control of the outputs.  
The frequencies of both the RCLK and the WCLK signals may vary from  
0 to fMAX with complete independence. There are no restrictions on the  
frequency of the one clock input with respect to the other.  
There are two possible timing modes of operation with these devices:  
IDT Standard mode and First Word Fall Through (FWFT) mode.  
In IDT Standard mode, the first word written to an empty FIFO will not  
appear on the data output lines unless a specific read operation is  
performed.Areadoperation,whichconsistsofactivatingRENandenabling  
InFWFTmode, the firstwordwrittentoanemptyFIFOis clockeddirectly  
to the data output lines after three transitions of the RCLK signal. A REN  
does not have to be asserted for accessing the first word. However,  
subsequentwords writtentotheFIFOdorequireaLOWonRENforaccess.  
The state of the FWFT/SI input during Master Reset determines the timing  
mode in use.  
Forapplications requiringmore data storage capacitythana single FIFO  
can provide, the FWFT timing mode permits depth expansion by chaining  
FIFOs in series (i.e. the data outputs of one FIFO are connected to the  
corresponding data inputs of the next). No external logic is required.  
These FIFOs have five flag pins, EF/OR (Empty Flag or Output Ready),  
FF/IR (Full Flag or Input Ready), HF (Half-full Flag), PAE (Programmable  
Almost-Emptyflag)andPAF (ProgrammableAlmost-Fullflag). TheEFand  
FF functions are selected in IDT Standard mode. The IR and OR functions  
areselectedinFWFTmode. HF,PAEandPAFarealwaysavailableforuse,  
irrespectiveoftimingmode.
