Function
1 LDI Read control input
Schmidt trigger input. At “L”, reset the internal digital circuit. At “H”, F2F modulation is possible.
3 F2F F2F output
F2F signal output that has amplified, differentiated and further waveform-shaped the magnetic head signal.
4 PKO Noise filter
Connect noise removing capacitor CNF between PKI and PKO.
5 PKI Differentiator input
Refer to PKO and AMP.
6 AMP Amplifier output
Connect resistor RPK and capacitor CPK between AMP and PKI.
7 HD2 Amplifier (–) input
Connect magnetic head between HD1 and HD2.
8 HD1 Amplifier (+) input
Connect magnetic head between HD1 and HD2.
9 VRF Reference voltage output Reference voltage output of Vcc 1/2
10 GND Grounding
11 RCP Read clock output
Clock pulse output after F2F modulation
12 RDT Read data output
Data output after F2F modulation
13 CLS Card travelling signal output Signal output indicating that card is travelling
14 INV Invert input
CLS, RDT and RCP output becomes “L” active at “H” (OPEN), and “H” active at “L”.
15 IB2 Ignore bit 2
Glance-over bit setting pin
16 IB1 Ignore bit 1
Glance-over bit setting pin
17 CX2 Oscillation capacitor
