Hardware Description - Interphase 4538 Hardware Reference Manual

Overview
The Interphase 4538 PMC E1/T1/J1 Communications Controller is a network interface PCI
Mezzanine Card (PMC) equipped with four software-selectable T1/E1/J1 interfaces (two
are provided on the front panel). The 4538 board is intended for 2G and 3G wireless
networks, Internet access, and Advanced Intelligent Network (AIN) applications.
This chapter provides the functional specification of the 4538. It describes how the different
main components of the board are arranged together.
The main components of the 4538 are:
• The PowerQUICC II™, a Motorola
• The Tundra PowerSpan™, a dedicated PCI bridge that controls the interface
• 4 MB of 8-bit FLASH EEPROM memory.
• 32 MB or 64 MB of 64-Bit SDRAM system memory
• The INFINEON QuadFALC™ framers, included in the 4538 communications
• The INTEL LXT971A, an IEEE compliant Fast Ethernet transceiver that supports
