DPMS (Display Power Management

Signaling) Detector for Green Monitor

Aug. 31, 1995

DESCRIPTION

The WT8048 is a 8 pin P-DIP package IC, designed for the application of Power Saving

Monitor or Green Monitor.

As per DPMS proposal, the WT8048 provides a detective circuit of monitor power

management for the convenience of designers in designing Power Saving Monitor.

FEATURES

{ Accepting two seperated H&V synchronous signals with positive/ negative polarity.

{ Capable of processing horizontal frequency between 0Hz to 100kHz, and vertical

frequency between 0Hz to 100Hz.

{ Power Saving mode - It can detect the conditions of monitor to decide which will be

selected as following: ON mode / STAND_BY mode / SUSPEND mode / OFF mode.

{ An Override mode is defined to override the DPMS function during the design, test,

burn-in manufacture or diagnostic process if desired.

APPLICATION

{ DPMS mode's detection for Green Monitor
