The C2000 MCU TMS320F28379D is operated in SDFM GPIO input qualification (3-sample window) option in mode 0 at 200 MHz system clock. The minimum setup and hold time are both 10 ns: tsu (SDDV-SDCH)M0(MIN) = 10 ns and th(SDCH-SDD)M0 (MIN) =10 ns are entered into the calculation tool. Furthermore, propagation delays of LVDS driver DSLVDS1047 and LVDS receiver DSLVDS1048 are entered for reference. With a 20-MHz clock signal at the isolated Delta-Sigma modulator clock input, which is the maximum clock frequency specified in the data sheet, the MCUs setup time requirements are violated when the data delay time tD of AMC1305L25 equals the minimum specification given in the data sheet with tD (MIN) = 0 ns, as shown in table 2.
Min. Setup Time @MCU | 5.6 ns |
Max. Setup Time @MCU | 23.3 ns |
Min. Hold Time @MCU | 26.7 ns |
Max. Hold Time @MCU | 44.4 ns |
