Serial Output Controller - SOC004GDP Space Systems - Telemetry Systems, Synchronizers, BERTS, Demodulaters, Modulators, Receivers, Frame Synchronizers, decommutator, Simulators

The SOC004, Serial Output Controller, is a full size ISA-PC/ AT printed circuit card. The Serial Output Controller generates a serial output data stream using either static or dynamically updated data loaded from the ISA-bus. With ample memory buffers on-board, any of several modes of data generation may be used. Data is output repeatedly or in bursts. Data to be serialized may be continuously updated by way of the ISA-bus master. A frequency synthesizer, resident on the module, allows precise bit rates to be generated.

Features

Bit rate 1 bps through 15 Mbps
13.2 in. x 4.5 in. ISA-PC/AT printed circuit card.
Dual 512 K x 16-bit simulation data memory buffers
Output format selectable, 4-16 bits / word, up to 512 K words / major cycle.

Output data code IRIG 106 compliant
Data placed into on-board Ping-Pong buffers, accessed as memory on the ISA bus.
End of Buffer interrupt - supports continuous (Ping-Pong) output operations.
TTL Serial data and clock outputs. (Optional RS-422 Outputs)
Can append NASCOM 22-bit CRC to block data.

Applications

Time Division Data Multiplexer
Telemetry Data Simulator

Command Generator

Operating Modes

Single Buffer
While data is output from buffer A, the alternate buffer B may be loaded with the new data. At the end of the current buffer (A), the SOC004 will switch to the alternate buffer (B).
Dual Buffer Output
The SOC004 automatically Ping-Pongs between buffers A and B. Alternately, output is derived from a single buffer until released to the other.
Burst
If the BURST MODE is selected, the SOC004 ends the data and clock transmission at the end of the currently selected buffer.
