Description
The PXB4221EV3.3 is an Interworking Element for 8 E1/T1 Lines and belongs to Infineon’s ATM chip set. It works together with framing and line interface components (such as Infineon’s QuadFALC PEB 22554) and serves as a gateway between Asynchronous Transfer Mode (ATM) networks and timeslot based PDH networks.
Specifications and features
- Full duplex ATM Packetizer/Depacketizer for 8 E1/T1 highways
- Configurable to T1 or E1 mode via an external pin
- 8 T1/E1 ports configurable independently to ATM or 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
- 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
Application Scenarios
The PXB4221EV3.3 can be used in various scenarios where there is a requirement to connect ATM networks with timeslot based PDH networks. Some of its applications include:
- Telecommunication networks
- Audio and video broadcasting systems
- Digital signal transmission systems
Comparison
