1. PCM55HP/1K Application Field and Working Principle

The PCM55HP/1K is a high-performance special-purpose device designed to meet the requirements of modern data acquisition and instrumentation processing. It offers a 16-bit, wide-bandwidth A/D conversion and 8-bit-parallel digital I/O. The operation of the PCM55HP/1K is based on Multiplexed Address/Data Read and Write (MADRW) protocol. MADRW combines two-phase data communication that provides reliable and efficient transmission of analog and digital data.

The PCM55HP/1K is a powerful multipurpose device used in a variety of data acquisition applications, including:

• Industrial control and automation
• Medical instrumentation
• Avionics
• Power generation
• Security systems
• Process control
• Data acquisition

The PCM55HP/1K uses MADRW to communicate between multiple Digital I/O channels and analog input channels to support its data acquisition capabilities. The MADRW protocol provides a single bus system with a continuous data stream and read/write control signals. Each data packet is strictly composed of a single address and data item. The protocol enables efficient data transfer of 16-bit words at speeds of up to 10 MHz. The MADRW protocol is an essential feature of the PCM55HP/1K and is necessary to achieve the highest performance.

The PCM55HP/1K also includes 8-bit digital I/O ports that are connected in a parallel bus system. The I/O ports can be configured to support a variety of digital I/O devices including Triggers, Counters, Timers, Temperature Sensors, Range Selectors, and many other digital instruments. The I/O ports can be configured for different data formats, byte widths, and logic levels. The port enable functions allow for simultaneous input and output operations.

The PCM55HP/1K features a hybrid analog-to-digital sampling circuitry, which enables the user to select the best A/D sampling rate for each application. The sampling rate can range from 1 kHz to 20 MHz and can be controlled by external software or hardware. The PCM55HP/1K also provides adjustable sample rate stabilization, which can help achieve accurate results in applications, such as audio frequency measurements or temperature sensing.

2. Conclusion

The PCM55HP/1K is a powerful and versatile special-purpose device designed to meet the requirements of modern data acquisition and instrumentation processing. Its MADRW protocol and 8-bit parallel digital I/O ports provide reliable and efficient transmission of analog and digital data. The device includes a hybrid analog-to-digital converter and adjustable sample rate stabilization. It is suitable for a variety of data acquisition applications, from industrial control and automation to medical instrumentation, avionics, power generation, security systems, process control and data acquisition.
