4.10 Digital Inputs / Outputs

All measurements were performed using the two-layer PCB CC1020EMX reference design. See Figure 6-1. The electrical specifications given for 868 MHz are also applicable for 902 to 928 MHz. TA = 25°C, AVDD = DVDD = 3.0 V, fC = 14.7456 MHz if nothing else stated.
PARAMETER MIN TYP MAX UNIT CONDITION
Logic "0" input voltage 0 0.3 × VDD V
Logic "1" input voltage 0.7 × VDD VDD V
Logic "0" output voltage 0 0.4 V Output current –2.0 mA,
3.0 V supply voltage
Logic "1" output voltage 2.5 VDD V Output current 2.0 mA,
3.0 V supply voltage
Logic "0" input current N/A –1 µA Input signal equals GND.
PSEL has an internal pullup resistor and during configuration the current will be –350 mA.
Logic "1" input current N/A 1 µA Input signal equals VDD
DIO setup time 20 ns TX mode, minimum time DIO must be ready before the positive edge of DCLK. Data should be set up on the negative edge of DCLK.
DIO hold time 10 ns TX mode, minimum time DIO must be held after the positive edge of DCLK. Data should be set up on the negative edge of DCLK.
