Triple, 6-Channel LCD Timing

Delay-Locked Loop

AD8389

PRODUCT FEATURES

High speed

Up to 85 MHz clock rate

Triple (R, G, B) output

Matched delay lines

Low power dissipation: 40 mW

Reference to rising or falling edge of MONITI input

Selectable loop delay

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.

Available in 48-lead 7 mm × 7 mm LFCSP

APPLICATIONS

LCD microdisplay horizontal timing

The AD8389 dissipates 40 mW nominal power. The AD8389 is

offered in a 48-lead 7 mm × 7 mm LFCSP package and operates

over the commercial temperature range of 0°C to 85°C.
