153 / 226 page  8.12.3.1 McBSP Electrical Data and Timing 8.12.3.1.1 McBSP Transmit and Receive Timing Section 8.12.3.1.1.1 shows the McBSP timing requirements. Section 8.12.3.1.1.2 shows the McBSP switching characteristics. Figure 8-64 and Figure 8-65 show the McBSP timing diagrams. 8.12.3.1.1.1 McBSP Timing Requirements NO.(1) (2) MIN MAX UNIT McBSP module clock (CLKG, CLKX, CLKR) range 1 kHz 25 MHz McBSP module cycle time (CLKG, CLKX, CLKR) range 40 ns 1 ms M11 tc(CKRX) Cycle time, CLKR/X CLKR/X ext 2P ns M12 tw(CKRX) Pulse duration, CLKR/X high or CLKR/X low CLKR/X ext P – 7 ns M13 tr(CKRX) Rise time, CLKR/X CLKR/X ext 7 ns M14 tf(CKRX) Fall time, CLKR/X CLKR/X ext 7 ns M15 tsu(FRH-CKRL) Setup time, external FSR high before CLKR low CLKR int 18 ns CLKR ext 2 M16 th(CKRL-FRH) Hold time, external FSR high after CLKR low CLKR int 0 ns CLKR ext 6 M17 tsu(DRV-CKRL) Setup time, DR valid before CLKR low CLKR int 18 ns CLKR ext 5 M18 th(CKRL-DRV) Hold time, DR valid after CLKR low CLKR int 0 ns CLKR ext 3 M19 tsu(FXH-CKXL) Setup time, external FSX high before CLKX low CLKX int 18 ns CLKX ext 2 M20 th(CKXL-FXH) Hold time, external FSX high after CLKX low CLKX int 0 ns CLKX ext 6 (1) Polarity bits CLKRP = CLKXP = FSRP = FSXP = 0. If the polarity of any of the signals is inverted, then the timing references of that signal are also inverted. (2) 2P = 1/CLKG in ns. CLKG is the output of sample rate generator mux. CLKG = CLKSRG / (1 + CLKGDV). CLKSRG can be LSPCLK, CLKX, CLKR as source. CLKSRG ≤ (SYSCLK/2). www.ti.com TMS320F28379D, TMS320F28379D-Q1, TMS320F28378D, TMS320F28377D TMS320F28377D-Q1, TMS320F28376D, TMS320F28375D, TMS320F28374D SPRS880O – DECEMBER 2013 – REVISED FEBRUARY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 153 Product Folder Links: TMS320F28379D TMS320F28379D-Q1 TMS320F28378D TMS320F28377D TMS320F28377D-Q1 TMS320F28376D TMS320F28375D TMS320F28374D |
