DEPTH EXPANSION

The IDT72420/72200/72210/72220/72230/72240 can be adapted to

applications when the requirements are for greater than 64/256/512/1,024/

2,048/4,096 words. Depth expansion is possible by using expansion logic to

direct the flow of data. A typical application would have the expansion logic

alternate data accesses from one device to the next in a sequential manner.

Please see the Application Note “DEPTH EXPANSION IDT'S

SYNCHRONOUS FIFOs USING RING COUNTER APPROACH” for details
