PRODUCTION DATA
The SCLK frequency is determined by the data volume of one frame and frame rate. In this application, the data volume V_Data is 30 × 32 × 48 bits × 4 = 184.32 Kb, the frame rate is 120 Hz. Suppose the data transmission efficiency is 0.8, the minimum frequency of SCLK must be: fSCLK = V_Data × fframe / 0.8. So the minimum SCLK frequency is 13.83 MHz with dual-edge transmission.
