PRODUCT DESCRIPTION

The AD8389 is a triple 6-channel LCD microdisplay delay locked timing loop. As part of a closed-loop system, the AD8389 maintains a constant delay between the common input, DXI, and each independent feedback reference, MONITxI. The AD8389 consists of a selectable fixed delay element, a phase detector, a charge pump, and six matched variable delay lines per color. The phase detector, charge pump, and master delay line form a closed loop when connected to a compatible LCD microdisplay. Five additional delay lines track the master for a complete set of matched timing signals.
