The period required by the retransmit operation is now fixed and short.
The first word data latency period, from the time the first word is written to
anemptyFIFOtothetimeitcanberead,isnowfixedandshort. (Thevariable
clock cycle counting delay associated with the latency period found on
previous SuperSync devices has been eliminated on this SuperSync
family.)
SuperSync FIFOs are particularly appropriate for networking, video,
telecommunications,datacommunicationsandotherapplicationsthatneedto
buffer large amounts of data.
TheinputportiscontrolledbyaWriteClock(WCLK)inputandaWriteEnable
(
WEN)input. DataiswrittenintotheFIFOoneveryrisingedgeofWCLKwhen
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
edgeofRCLKwhen
RENisasserted. AnOutputEnable(OE)inputisprovided
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 one clock input with respect to the other.
NOTE:
1. DC = Don’t Care. Must be tied to GND or VCC, cannot be left open.
