Ordering Information

MEB90500 Advance Information Functional Requirements Interface and Mechanical - this evaluation kit offers two PC-compatible boards with an ISA interface. The boards are fitted with an MVIP 40-pin connector, one RJ-11 jack for handset connection, and an optical module connector for the ATM 155 connection. Hardware Figure 1 outlines the physical characteristics of each MT90500 Evaluation card available in the kit. The evaluation board is a PC-compatible 8/16-bit ISA board which provides the following interfaces:

• ATM155 MMF optical interface (ATM)
• MVIP compatibility (TDM)
• Handset Connector (Local TDM) The specific components used are shown in Figure 1. The FPGA module emulates a Motorola/Intel processor via the ISA bus interface. This module emulates the functionality of aµprocessor and integrates all the other logic functions that are required to operate the board. It provides the necessary control for the operation of the Mitel codec (MT9160), LDX (MT90820) and external PLL (MT9041) as required. The Mitel MT90820 LDX device allows the user to generate 64 kbps or nx64 kbps patterns to the MT90500 device, at 2.048, 4.096 and 8.192 Mbps. The card contains an MT9160 codec interfacing with a telephone handset for demo purposes. A GUI interface is provided to operate the codec. The MCEK is provided with two Synchronous SRAM (64K x 18) used by the MT90500 to externally store its control and data structures. The MCEK is built with the tools necessary to exercise directly most of the MT90500 functionality:
• µprocessor interface (headers on control signals)
• external SSRAM interface
• TDM interface (external via the MVIP connector; local via headers)
• UTOPIA interface (primary and auxiliary interface headers)
• JTAG port (headers)
• TDM clock recovery and generation The MCEK also provides the customer with the ability to use the following clock modes:
• Adaptive
• Freerun
• Synchronized to the 155Mbps PHY device (receive only) Note: For SYNC to PHY modes, the MCEK allows the customer to access the 8kHz output from the PHY chip. In addition, this kit contains a software algorithm for an adaptive clock recovery method. In regards to clock generation and recovery, the cards can either generate clocks in master mode or receive input clocks in slave mode. Software, Device Drivers Three software modules are provided:
• A demonstration program which allows audio communications between two cards connected back to back via an ATM crossover cable or an ATM switch. The audio communication will be provided on each card via a telephone handset (codec on local bus). The software demonstrates how to set up one channel per VC in structured data transfer (SDT) mode. The clock mode (one of the 3 mentioned above) can be selected by the user. This demonstration program also allows the user to configure the MT90500 for multiple channels per VC in structured data transfer (SDT) mode or pointer- free mode, including the option for the clock mode selection. The pertinent documented C source code for this demo software is provided. This software runs under Windows NT.
• A demonstration program showing the power of the MT90500. To accomplish this objective, the application transmits 1024 channels simultaneously. The pertinent documented C source code for this demonstration is provided. The driver initializes the card, including the FPGA.
• A diagnostic module which provides access to registers within the Mitel MT90500 and its external memory. The diagnostic software is able to run while the other software is operating. This software runs under Windows NT.
