This application note provides information on how to use National Semiconductor's DS90CR218A and LM98714 devices to create low EMI, high performance, long distance (16-bit, 45MSPS) LVDS links.
This application note explains how the National Semiconductor DS90CR218A LVDS channel‑link receiver works together with the LM98714 16‑bit, 45 MSPS analog front‑end to form a high‑performance LVDS data link for image sensors such as CCD/CIS. It covers the system architecture, LVDS advantages, timing considerations, and PCB layout recommendations.
The document provides design guidance on setup time, hold time, receiver offset margin (RSKM), and termination requirements, and includes reference tables and typical values for engineers designing LVDS interfaces. This manual is written in Chinese.
| Input clock frequency range | 12 to 85 MHz |
|---|---|
| RSKM typical value (LM98714 as transmitter) | 0.968 ns |
The typical receiver offset margin (RSKM) is 0.968 ns.
A typical termination resistor value is 100 Ω.
