14 / 91 page  Not Recommended for New Designs NRND CC1021 SWRS045D – JANUARY 2006 – REVISED JANUARY 2015 www.ti.com Digital Inputs / Outputs (continued) 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 TX mode, minimum time DIO must be held after the DIO hold time 10 ns positive edge of DCLK. Data should be set up on the negative edge of DCLK. Serial interface See Table 5-1 for more (PCLK, PDI, PDO and PSEL) details timing specification 0 V on LNA_EN, PA_EN pins 0.90 mA 0.5 V on LNA_EN, PA_EN pins 0.87 mA Source current 1.0 V on LNA_EN, PA_EN pins 0.81 mA Pin drive, 1.5 V on LNA_EN, PA_EN pins 0.69 mA See Figure 5-32 for more LNA_EN, details. 3.0 V on LNA_EN, PA_EN pins 0.93 mA PA_EN 2.5 V on LNA_EN, PA_EN pins 0.92 mA Sink current 2.0 V on LNA_EN, PA_EN pins 0.89 mA 1.5 V on LNA_EN, PA_EN pins 0.79 mA 4.11 Current Consumption All measurements were performed using the two-layer PCB CC1020EMX reference design.
