DESCRIPTION:
The IDT72V275/72V285 are exceptionally deep, high speed, CMOS
First-In-First-Out (FIFO) memories with clocked read and write controls.
These FIFOs offer numerous improvements over previous SuperSync
FIFOs, including the following:
The limitation of the frequency of one clock input with respect to the other
has been removed. The Frequency Select pin (FS) has been removed,
thus it is no longer necessary to select which of the two clock inputs, RCLK
or WCLK, is running at the higher frequency.
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
an empty FIFO to the time it can be read, is now fixed and short. (The
variable 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 network, video, telecom-
munications,datacommunicationsandotherapplicationsthatneedtobuffer
large amounts of data.
