TSB14C01APMR

Controllers Overview

The TSB14C01APMR is a single-port node transceiver designed for backplane-based IEEE 1394 (FireWire) networks. It supports S50 and S100 data rates of 50 Mbits/s and 100 Mbits/s, respectively. The device operates on a single 5-V supply and interfaces with a link-layer controller via two parallel signal lines at 25/50 MHz. It includes logic for system initialization, arbitration, and data-strobe bit-level encoding. The PM package variant provides an operating temperature range of 0°C to 70°C.

Controllers Feature Summary

• Supports provisions of the IEEE 1394-1995 standard for high-performance serial bus
• Provides separate transmitter and receiver terminals for greater flexibility
• Performs system initialization and arbitration functions internally
• Includes encode and decode functions for data-strobe bit-level encoding

Controllers Applications

• Implementation of single port nodes in backplane-based 1394 networks
• System initialization and arbitration in digital mobile radio communications units
• Interfacing with link-layer controllers such as the TSB12C01A

Controllers Procurement Notes

Verify that the specific suffix 'PM' corresponds to the Thin Quad Flat Pack package and the required commercial temperature range of 0°C to 70°C. Confirm that the external driver circuitry is supplied by the customer, as the TSB14C01A does not drive the backplane directly. Ensure the design accommodates the necessary 64-pin footprint and power distribution for a 5-V single supply operation.

Controllers Selection Notes

Select this component when implementing a backplane-based FireWire node requiring S50 or S100 speeds. Choose the PM package for commercial environments within the 0°C to 70°C range. For industrial applications requiring -40°C to 85°C, consider the TSB14C01AI variant. Ensure the design includes an external 98.304-MHz or 49.152-MHz reference oscillator input for proper clock synchronization.

Controllers Part Context

The TSB14C01A belongs to the Texas Instruments 1394 PHY family, specifically designed for backplane implementations. It complements the TSB12C01A link-layer controller to form a complete physical layer solution. This series enables interoperability with FireWire standards and supports both cable and backplane environments through configurable priority and ID settings.
