Description
Description
the IDT77V400 Switching Memory, forms the core control logic and
switch fabric for a 1.2Gbps non-blocking ATM switch. The IDT77V500
manages all of the switch traffic moving through the IDT77V400,
commanding the storage of incoming ATM cells and interpreting and
modifying the cell header information as necessary for data flow through
the switch. It then uses the header information, including priority indica-
tors, to queue and direct the individual cells for transmission out the
appropriate output port of the IDT77V400.
The IDT77V500 ATM Cell Based Switch Controller, when paired with
Control
One IDT77V500 can manage up to eight IDT77V400's
without derating for larger switch configurations
Industrial temperature range (-40° C to +85° C) is available
Single +3.3V ± 300mV power supply
Available in a 100-pin Thin Plastic Quad Flat Pack (TQFP)
