Electrical Specifications
Electrical Specifications
Unless otherwise stated, the following specifications apply under the following condi-
tions: VDD = 1.8V – 0.10/+0.15; VDD_IO = VDD_PLL = VAA = VAA_PIX = 2.8V ± 0.3V;
VDD_SLVS = 0.4V – 0.1/+0.2; T_A = -30°C to +85°C-40°C to +105°C; output load = 10pF;
frequency = 74.25 MHz; HiSPi off.
Two-Wire Serial Register Interface
The electrical characteristics of the two-wire serial register interface (SCLK, SDATA) are
shown in Figure 13 and Table 7.
