Function
Schmidt trigger input. At “L”, reset the internal digital circuit. At “H”,
F2F modulation is possible.
F2F signal output that has amplified, differentiated and further
waveform-shaped the magnetic head signal.
Connect noise removing capacitor CNF between PKI and PKO.
Refer to PKO and AMP.
Connect resistor RPK and capacitor CPK between AMP and PKI.
Connect magnetic head between HD1 and HD2.
Connect magnetic head between HD1 and HD2.
Reference voltage output of VCC 1/2
Clock pulse output after F2F modulation
Data output after F2F modulation
Signal output indicating that card is travelling
CLS, RDT and RCP output becomes “L” active at “H” (OPEN), and “H”
active at “L”.
