S1D2147A01

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 Vertical processing East/West signal processing block B+ controller Safety blanking output Device Package 42-SDIP Operation Temperature 0 °C — 70 °C ORDERING INFORMATION FEATURES (HORIZONTAL) Dual Pll concept Self-adaptative (30 to 70kHz) X-ray protection input DC adjustable duty-cycle Internal 1st PLL lock/unlock information Wide range DC controlled H-position ON/OFF switch (for PWR management) Two H-drive polarities (VERTICAL) Vertical ramp generator 50 to 120Hz AGC Loop DC controlled V-amp, V-pos, S-amp & S-centring ON/OFF Switch (B+ REGULATOR) Internal PWM generator for B+ current mode step-up conveter DC adjustable B+ voltage Output pulse synchronised on horizontal frequency Internal MAX current limitation S1D2147A01-A0B0 (GENERAL) Accept Positive or Negative Horizontal & Vertical sync polarities Separate H & V TTL input Safety blanking output (EWPCC) Vertical parabola generator with DC controlled keystone & amplitude 0 S1D2147A01 DEFLECTIONPROCESSORFORMULT...
