Signal Conditioner for Multi-Rate Data Lane Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Legacy communication standards face obsolescence as newer, faster standards develop, lacking accommodation for older standards within new architectures, which limits the compatibility and extends the service life of legacy devices.
Innovation Solution
A signal conditioning arrangement that receives input signals at different data rates and drives output signals onto output ports with multiple data lanes, enabling the mapping, translation, or transfer of legacy communications onto newer architectures, thereby supporting single-connection docking solutions for electronic devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If newer, faster communication standards are developed, then data transmission speed is improved, but compatibility with legacy standards deteriorates
Solution Approach 1:
The signal conditioning arrangement is designed to handle multiple communication standards simultaneously. The processing component can receive signals from both legacy standards (e.g., USB 2.0 at lower data rates) and newer standards (e.g., USB 3.0 at higher data rates) through the same physical interface, making the system universally compatible across different generations of communication protocols
Solution Approach 2:
The signal conditioning arrangement acts as an intermediary device between legacy devices and newer communication infrastructure. It receives legacy signals, conditions them appropriately, and transmits them over modern high-speed data lanes, thereby mediating the interaction between incompatible standards and enabling legacy devices to communicate through newer architectures
2Productivity
If legacy standards are not accommodated in newer standards, then newer standards achieve higher performance, but legacy devices face obsolescence
Solution Approach 1:
The signal conditioning arrangement performs preliminary signal conditioning and adaptation before transmission over high-speed lanes. By pre-processing legacy signals to match the requirements of newer standards, the system enables legacy devices to maintain operational relevance longer, extending their service life without compromising the performance benefits of newer communication architectures
3Adaptability or versatility
If multiple physical connections are used to support different data communications, then compatibility with various standards is improved, but device complexity increases
Solution Approach 1:
The signal conditioning arrangement merges support for multiple communication standards into a single physical interface. Instead of requiring separate physical connections for USB 2.0, USB 3.0, and other standards, the device consolidates these capabilities into one docking connector that can handle different protocols through signal conditioning and lane allocation, thereby reducing physical complexity while maintaining versatility

AI summary
A method, signal conditioning circuit, and system are disclosed to perform signal conditioning using a processing component coupled with at least first and second inputs. The processing component is further coupled with a first output port including first and second data lanes operable at different data rates. The method includes receiving, via the first input and at a first data rate, data included in a first input signal, and receiving, via the second input and at a second data rate different from the first data rate, data included in a second input signal. The method further includes driving, based on the first and second input signals, a first output signal onto the first output port, which includes transmitting the data included in the first input signal on the first data lane, and transmitting the data included in the second input signal on the second data lane.
