SuperSync FIFOs are particularly appropriate for network, video, telecommu-
nications,datacommunicationsandotherapplicationsthatneedtobufferlarge
amountsofdata.
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
WCLK when
WEN is asserted. The output port is controlled by a Read
Clock (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
tofMAXwithcompleteindependence. Therearenorestrictionsonthefrequency
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. A read operation, which consists of activating
REN and
enabling a rising RCLK edge, will shift the word from internal memory to the
data output lines.
