WT8048
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

Function
Input terminal of horizontal
synchronous signal
Input terminal of vertical
synchronous signal
A clock generator circuit is built
into the chip. So, if a resonator is
connected to OSC pin and
ground, a clock signal can be
obtained.
