SATA Connector Host Detection for Protocol Adaptation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high cost and complexity of using dongles for SATA/USB protocol conversion in data storage device cables increase manufacturing and testing burdens, as they require multiple test stations and interface cables compatible with different protocols, and swapping PCBs with different connectors is time-consuming and costly.
Innovation Solution
A data storage device with a SATA connector and control circuitry that evaluates specific pins to detect host types, configuring a communication module to operate using either SATA or non-SATA protocols, allowing direct connection to non-SATA hosts without a dongle and eliminating the need for PCB swaps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dongle is used to implement SATA/USB protocol conversion, then compatibility with non-SATA hosts is improved, but cable cost and device complexity increase
Solution Approach 1:
The data storage device is designed with a universal SATA connector that can detect and adapt to both SATA and non-SATA hosts. The control circuitry evaluates pin states to determine host type and configures the communication module accordingly, allowing a single device to function with multiple host types without requiring different cables or dongles.
Solution Approach 2:
The control circuitry acts as an intermediary between the SATA connector and the communication module. It evaluates the pin states of the SATA connector to detect host type and mediates the configuration of the communication module to operate in either SATA or non-SATA mode, eliminating the need for external dongles.
2Adaptability or versatility
If a dongle is used for protocol conversion, then non-SATA host support is improved, but manufacturing and testing costs increase
Solution Approach 1:
A single data storage device design supports both SATA and non-SATA hosts through integrated host type detection and adaptive communication module configuration. This universality eliminates the need for separate dongle components and multiple PCB variants, reducing manufacturing complexity and costs.
Solution Approach 2:
The host type detection and protocol adaptation functionality is extracted from external dongles and integrated into the data storage device's control circuitry. This consolidation removes the need for separate dongle manufacturing and assembly processes.
3Adaptability or versatility
If multiple PCB types with different connectors are used, then support for different host types is improved, but manufacturing time and complexity increase
Solution Approach 1:
Instead of manufacturing multiple PCB types with different connectors for SATA and non-SATA hosts, the invention uses a single PCB design with a SATA connector and integrated control circuitry that detects host type and adapts the communication module accordingly. This significantly reduces manufacturing steps and improves productivity.
Solution Approach 2:
The communication module is designed to be dynamically reconfigurable based on detected host type. The control circuitry evaluates pin states and dynamically configures the communication module to operate in SATA or non-SATA mode, allowing a single static PCB to support multiple host types without requiring physical swaps or multiple designs.
Data Source
AI summary
A data storage device (DSD) is disclosed comprising a SATA connector and control circuitry comprising a communication module for communicating with a host. At least one pin of the SATA connector is evaluated to detect a host type. When the host type is SATA, the communication module is configured to operate according to a SATA protocol, and when the host type is non-SATA, the communication module is configured to operate according to a non-SATA protocol.
