FUNCTIONAL DESCRIPTION  
FEATURES  
The QS6810A is a full-duplex high-speed 4:1 ATM  
cell multiplexer/demultiplexer with built-in FIFO buff-  
ering.Itprovidesfiveindustry-standardUTOPIAports  
to connect to a variety of physical-layer and adapta-  
tion-layerdevices.Fourfull-duplexATMdatastreams  
of up to 200Mb/s can be multiplexed/demultiplexed  
into one data stream of up to 800Mb/s. Up to eight  
QS6810A's can be connected in parallel to make  
wider multiplexer/demultiplexers, up to 31:1. (Note:  
Port address 11111b is used in the system for bus  
arbitration,andthusisunavailableasaportaddress.)  
• TableFull-duplex 4:1 ATM cell mux/demux  
• High speed, up to 800-Mb/s transfer rate  
• 18-Kbit FIFO buffering on chip  
• Expandable up to 31-to-1 mux/demux  
• Variable cell length for routing tag insertion  
• Byte- and word-width UTOPIA data ports  
• Generic microprocessor interface for  
configuration, testing, network management  
• Loopback test modes for network/system  
verification  
• JTAG port for boundary-scan testing  
• Advanced low-power CMOS technology  
• Space-saving 208-pin QFP package  
• 5V power supply  
The QS6810A (see Figure 1) can be used as an  
inexpensive concentrator or fanout expander to  
combine multiple low- to medium-speed ATM cell  
streams into higher-speed streams. This allows  
various ATM data rates to be efficiently mixed and  
matched within the same local switch fabric. The  
partcanalsobeusedasabuildingblockforlow-cost  
non-blocking crosspoint switches. (See APPLICA-  
TION EXAMPLES.)  
• –40°C to 85°C operating temperature  
Each QS6810A has five ATM UTOPIA interface  
ports. Ports A, B, C, and D are byte-wide UTOPIA  
Level 1 ports while Port W is a programmable byte-  
or word-wide UTOPIA Level 2–compatible port.  
Data parity bit transfers are also supported, one  
parity bit for each byte if bit 6 of the configuration  
register is set to “0”, or one parity per word if bit 6 is  
set to “1”.
