Framer DS1/E1|T1/E1 3.3V 256-Pin PBGA

8 E1/T1 Lines PXB 4219E is a member of Infineon’s ATM chip set. Together with framing and line interface components the IWE8 serves as gateway between Asynchronous Transfer Mode (ATM) networks and timeslot based PDH networks. Each of the 8 E1 or T1 input and output ports can be configured independently to operate in one of two basic modes ATM Mode and AAL Mode.

• 16-bit generic microprocessor interface for control and configuration of the chip runs either in Intel 386EX or Motorola compatible mode
• External synchronous Flow-Through SSRAM 1 x 64k x 33 bit or 1 x 64k x 32 bit required
• Build-in data path loops for test
• Cell insertion/extraction via microprocessor interface
• 3.3 Volt power supply with 5 Volt tolerant inputs
• Typical power dissipation 1 Watt
• P-BGA-256 package
• Temperature range from -40° to +85°C
