S1D2147A01-A0B0, DEFLECTION PROCESSOR FOR MULTISYNC MONITORS

Table 1.

Pin Description Pin No 1 2 Pin Name PLL2C H-DUTY Second PLL Loop Filter DC Control of Horizontal Drive Output Pulse Duty-cycle.

If this pin grounded, the horizontal and vertical outputs are inhibited.

By connecting a capacitor on the this pin a soft-start function may be realized on h-drive

DEFLECTION PROCESSOR FOR MULTISYNC MONITORS S1D2147A01 DEFLECTION PROCESSOR 42-SDIP-600 The S1D2147A01is a monolithic integrated circuit assembled in a 42 pins shrunk dual in line plastic package.

The goal of this IC is to control all the functions related to the horizontal and vertical deflection in multimodes or multisync monitors.

FUNCTIONS Positive or Negative sync polarities Auto-sync horizontal processing H-PLL lock/unlock identification Auto-sync
