PREMODULATION FILTER

MODEL PMF12

DESCRIPTION

THE PMF12 PREMODULATION FILTER IS DESIGNED TO SUPPLY ADDITIONAL CURRENT DRIVE FOR LOW IMPEDANCE LOADS (COAX CABLE) AT HIGH BIT RATES. THE PMF12 CAN DRIVE A 75 OHM LOAD IN PARALLEL WITH 1000pf AT ±2.5V, 2 MEGA BIT NRZ-L. CONTACT FACTORY FOR INCREASED DRIVE CAPABILITY. THE INPUT LEVEL DETECTOR REMOVES UNDESIRABLE NOISE SPIKES FROM THE PCM DATA PRIOR TO FILTERING.
