Test Methods
(supplementary)
Note: Due to the relation with RFRP detection frequency, use feed search (track cross speed) at 80 kHz or less.
1. Test method for RFRP detection frequency characteristic and detection time constant
(1)
Detection frequency
Set to 0dB the maximum output amplitude of the RFRP pin in relation to the operating reference
voltage 1 (V
OP1RP
) when the sine wave shown in the figure below is input via a capacitor (Cin 1 F)
to the RFRPIN pin and specify a frequency whose amplitude is 3dB.
(2)
Detection time constant
Specify the time constant for peak and bottom detection frequencies when the square wave shown
in the figure below is input via a capacitor (Cin 1 F) to the RFRPIN pin at the slew rate of the
RFRP pin output sawtooth wave.
RFRPIN input: 1.2 Vpp
f 5 kHz (SEL HiZ or V
CC
)
RFRP output
Specify by slew rate here
37 V/ms (SEL HiZ or V
CC
)
RFRPIN input: 1.2 Vpp
RFRP output amplitude: [V]
Operating reference voltage 1 (V
OP1RP
)
35
Specify by amplitude
equivalent to 3dB
Set this amplitude
to 0dB
RFRPIN input frequency [kHz]
Detection frequency
