Description

The MC92501GC is one member of the MC92501 family which designed as the Asynchronous Transfer Mode (ATM) layer device that composed of dedicated high-performance ingress and egress cell processors of MC92501GC combined with UTOPIA Level 2-compliant physical (PHY) and switch interface ports (see Block Diagram). This device consists of user end stations that transmit and receive 53-byte data cells on virtual connections and the switch of it contains a high-speed switching fabric that connects multiple line cards.

Features of the MC92501GC are:(1)support for CLP transparency;(2)change ABR RM cell priority;(3)supports both partial packet discard (PPD) and early packet discard (EPD);(4)UTOPIA level 2 PHY interface and UTOPIA ATM layer interface;(5)selective discard CLP=1 (or CLP=0+1) flow on selected connections;(6)provides ABR relative rate marking and EFCI marking according to TM 4.0;(7)implements ATM layer functions for broadband ISDN according to ATM forum UNI 4.0 and TM 4.0 speciÞcations, ITU recommendations, and bellcore recommendations.

The absolute maximum ratings of the MC92501GC can be summarized as:(1)DC supply voltage:-0.5 to 3.8 V;(2)DC input voltage (5 V tolerant):-0.5 to 5.8 V;(3)DC output voltage:-0.5 to VDD+0.5 V;(4)DC current drain per pin, any single input or output:±50 mA;(5)DC current drain VDD and Vss pins:±100 mA;(6)storage temperature:-65 to 150 °C;(7)lead temperature (10-second soldering):300 °C.
