C.4 Internal Interfaces
C.4.1 Introduction
This section provides a description of the internal interfaces between the sonar
processor and the transceiver unit. There are three interfaces for standalone
operation: Power, Uplink Data and Downlink Data. Those interfaces are
described below.
C.4.2 Power
The transceiver unit requires a nominal 24VDC for operation, however a voltage
range of 22 to 30 volts is acceptable.
C.4.3 Uplink Data
The uplink between the transceiver unit and the sonar processor is a high-speed
digital data stream running at 36.4Mbps. Each frame contains 512 bytes
transmitted at a frame rate of 7.109kHz.
Each byte is split into two 4-bit nibbles with the low nibble sent first. Nibbles are
4-to-5 encoded, NRZI modulated, and uplinked at 36.4Mbps. The uplink driver
generates 0.7Vp-p signal into a 75-ohm coaxial cable.
