This means the loop response can be optimized to the line frequency of each particular video format input to the THS8083. The digital PLL can also operate in open-loop as an accurate frequency synthesizer, avoiding frequency drift on the pixel clock when the input video signal is lost. The PLL's clock frequency and the frequencies of incoming horizontal and vertical sync signals can be monitored over the serial interface, relieving the system microcontroller from this task. As a result, TI's digital PLL improves stability and reduces system cost. Tools and Support Several LCD scaler makers have developed production-ready LCD monitor reference designs using TI's THS8083.
Reference designs from others are currently in development.
