WT8043N20P8

Synchronous Signal discriminator for Multi-Sync Display Monitor

Unspecified 

WT8043

Application Information

Name

Function

OSCin

OSCout

HSin

A clock generating circuit is built into the chip. So if

a resonator is connected to OSCin / OSCout, a clock

signal can be obtained

Referent to OSCin pin

Input terminal of horizontal synchronous Signal

VSin

Input terminal of vertical synchronous Signal

H_out

Output pin, active low, fixed polarity of original

H_sync signal w/ same pulse width

1280 x 1024 1280x1024 mode control output

V_OUT

F60K

F52K

Output pin, active low, fixed polarity of original

V_sync signal w/ same pulse width

H, frequency input 60k discrimination > 60k then

active low, < 60k then high

> 52k then active low, < 52k then high

F45K

> 45k then active low, < 45k then high

F36K

> 36k then active low, < 36k then high

Vss

F33K

Ground

> 33k then active low, < 33k then high

640 x 350

Mode seclect control output, if IBM VGA 640x350

mode, or VESA VGA 640x350 mode, then active

low, else high state output
