the duty cycle of the pwm signal can be selected to be either 5% or 10%. dim-to-of feature is fully supported with a minimum hysteresis of 200 mv between dim-to-dark and dim-to-light. embedded digital signal processing maintains minimum variations from device to device.

3 functional description typical application circuit figure 2 typical application circuit note : the diode marked with * is for the protection of the r dim+ -pin when active dimming is used. this is because the voltage on this pin is not allowed to be higher than v cc +0.5v. it is advised to use a low leakage, low reverse current schottky-diode in order to not influence the dimming performance (e.g. mmsd301t1g). note : the capacitor connected to the r dim+ -pin reduces the amount of coupled noise to the dimming signal. the size of this capacitance should be in the range of 2.2 - 10 nf (typ. 4.7 nf), where a small capacitor allows steeper edges of the dimming signal, a larger capacitor enhances the noise reduction.

the output to the normal operating voltage. this should also bring the v cc supply voltage to the normal operating area of the CDM10VD device where all parameters are in specification again. figure 5 extended v cc range CDM10VD flexible 0-10v dimming solution functional description datasheet 8 v1.1 2017-08-02
variable frequency pwm input mode CDM10VD device can be operated in a 'frequency conversion input mode'. in this mode the pwm input signal on r dim+ with frequencies between 100 hz and 3 khz will be converted to 1 khz signal on i out . the duty cycle between input and output signals remain at the same level. the configuration and conditions are described below. variable frequency mode conditions figure 6 timing for the variable frequency pwm input mode table 4 conditions for the variable frequency pwm input mode condition name min nom max r dimh r dim+ high value 9.6 v v cc +0,5v r diml r dim+ low value -0.5 v 0.0 v 0.5 v i outh i out high value r iout * i iout 1 i outl i out low value 0.0 v t in period input signal 0.33 ms 1.0 ms 10.0 ms t out period ouput signal 1.0 ms - 5 % 1.0 ms 1.0ms + 5 % t r rising edge time 1.8 s t f falling edge time 1.8 s note : 1 r iout is the resistance connected between the i out and the gnd-pin. i out is 1 ma or 5 ma dependent on the CDM10VD version. once the CDM10VD detects the frequency in the range 100 hz and 3 khz on the r dim+ input the internal fsm will lock afer min eight input signal periods. in this time the input r dim+ signal is provided to the i out directly, see figure 7 .

figure 7 lock phase default mode backup mode to avoid the i out behavior during lock phase in default mode, there is an additional option described below. in normal operation pin 5 has to be connected to the gnd level. in this mode the CDM10VD selects automatically between the standard hysteresis mode and the frequency conversion mode depending on the input signal on r dim+ . leaving the pin 5 unconnected, the cmd10vd device will switch directly to the frequency conversion mode and the i out pin will be tied to gnd during the frequency lock phase, see figure 8 . in this mode the standard hysteresis mode cannot be used. figure 8 lock phase backup mode CDM10VD flexible 0-10v dimming solution functional description datasheet 10 v1.1 2017-08-02
