Synchronous Signal Discriminator
for Multi-Sync Display Monitor
PT 8501
PT 8501 is a frequency discriminator IC utilizing CMOS Technology specially
designed for multi-sync display monitors. It supports a wide variety of display
modes -- from VGA‘s 640 x 350 to work station’s 1280 x 1024. By checking the
frequency and/or polarity of the horizontal and/or vertical synchronous signals,
PT 8501 can decide the proper display mode. It then drives the corresponding
output pins from high impedance to low level. PT8501 also sends out negative
polarity horizontal/vertical synchronous signals. PT8501’s highly comprehensive
features make it very reliable in performance.
