Aitech M457 - Telemetry PCM, Serial and Discrete I/O PMC

Provides Multiple Avionics Style Communication Protocols (MILSTD-1553, ARINC-429 and Serial I/O).

Introduction

The M457 is a general-purpose communication PMC, supporting Pulse Code Modulation (PCM) telemetry, high-speed serial communication (Synchronous/Asynchronous) and discrete I/O. 

The M457 I/O capabilities include one PCM engine, up to 6 high-speed serial channels and up to 16 discrete I/O channels.

The PCM engine is capable of telemetry data stream transmission in a predefined format. These transmission formats includes NRZ, RNRZ, RZ, BI? and DM).

The M457 PMC serial channels are independent high-speed synchronous/asynchronous channels supporting bit rates of up to 10Mbps (2Mbps in ASYNC mode).

Data transferred over the PCI bus to/from the carrier board system memory is performed using high performance DMA engines integrated in the PowerQuicc II controller.

The M457 PMC operates independently and requires only minimal intervention by the host, thus maximizing host performance.
