application are stored in 512MB of compact FLASH memory. The IDE interface

provides the data path between the processor & Sonar Interface Board (SIB).

3.2. Sonar Interface Board (Tiger Boards)

The Sonar Interface Board Set (SIB) is the real-time controller for sonar processing. It

includes transmit waveform tables and multiple channels of 10-bit high speed D/A

converters, support for external and internal triggers, and support for multiple sonar ADC

converters. It was designed to support a combined sonar system (with both sub-bottom

as well as multi-frequency side-scan capability), or to be used single channel as a basic

sub-bottom controller. At periodic intervals it generates the transmit waveform(s), and it

continuously buffers ADC data.

These sonar interface boards represent a new generation of reengineered and optimized

sonar electronics. This tiger board set is designed to address a broad spectrum of sonar

applications from a common and well tested base of components. Among the features of

this generation are lower power consumption, higher speeds, smaller form factors, and

high analog sensitivity / minimum noise electronics for improved operating ranges.

The sonar interface board is actually comprised of a three board set of cards. The three

board set is made up of SB Carrier Board, Sub-Bottom Acquisition Board, and

Sonar/IDE Interface Board.

3.2.1. SB Carrier Board

This board has the same physically size as an industry standard full slot PCI card. There

are two BNC connectors (J1-Triger-In & J3-Triger-Out) and female connectors on either

side for mating with the other two boards in the card set. An on board DC-DC converter

provides the +12 volts to the preamp in the tow fish.
