The SIA-2322 Serial Interface Adapter provides a means of interfacing the System Two Audio Measurement System to a variety of data acquisition, reconstruction and communication hardware that utilize a serial bus for the exchange of data. The SIA greatly increases System Two's flexibility in interfacing to serial systems for a wide range of tests and measurementsThe SIA consists of a parallel-to-serial transmitter and a serial-to-parallel receiver, each completely independent of the other. Since few serial communication standards exist, flexibility and ease of use were of primary concern in the design of the SIA. Some of the primary features provided by the SIA are:
Serial word length support of 8 to 32 bits, one or two channels (time multiplexed);
System Two data word length support of 8 to 24 bits, with optional 0 or 1 padding, LSB or MSB extension;
Left- or right-justified data within the serial data frame;
Data transmission and reception independently selectable as LSB- or MSB-first;
Independently programmable word clock transition timing within the data frame, with bit-wide and word-wide clock widths;
Independently programmable bit and word clock sources (internal or external);
TTL and CMOS logic level support on all inputs and outputs;
Logic polarity control of data, word clocks and bit clocks.
