29 / 147 page  8.13 Clock Specifications 8.13.1 Device Clock Table This section provides the timing requirements and switching characteristics for the various clock options available on the 2802x MCUs. Section 8.13.1.1, Section 8.13.1.2, and Section 8.13.1.3 list the cycle times of various clocks. 8.13.1.1 2802x Clock Table and Nomenclature (40-MHz Devices) MIN NOM MAX UNIT SYSCLKOUT tc(SCO), Cycle time 25 500 ns Frequency 2 40 MHz LSPCLK(1) tc(LCO), Cycle time 25 100(2) ns Frequency 10(2) 40 MHz ADC clock tc(ADCCLK), Cycle time 25 ns Frequency 40 MHz (1) Lower LSPCLK will reduce device power consumption. (2) This is the default reset value if SYSCLKOUT = 40 MHz. 8.13.1.2 2802x Clock Table and Nomenclature (50-MHz Devices) MIN NOM MAX UNIT SYSCLKOUT tc(SCO), Cycle time 20 500 ns Frequency 2 50 MHz LSPCLK(1) tc(LCO), Cycle time 20 80(2) ns Frequency 12.5(2) 50 MHz ADC clock tc(ADCCLK), Cycle time 20 ns Frequency 50 MHz (1) Lower LSPCLK will reduce device power consumption. (2) This is the default reset value if SYSCLKOUT = 50 MHz. 8.13.1.3 2802x Clock Table and Nomenclature (60-MHz Devices) MIN NOM MAX UNIT SYSCLKOUT tc(SCO), Cycle time 16.67 500 ns Frequency 2 60 MHz LSPCLK(1) tc(LCO), Cycle time 16.67 66.67(2) ns Frequency 15(2) 60 MHz ADC clock tc(ADCCLK), Cycle time 16.67 ns Frequency 60 MHz (1) Lower LSPCLK will reduce device power consumption. (2) This is the default reset value if SYSCLKOUT = 60 MHz. www.ti.com TMS320F28027, TMS320F28027-Q1, TMS320F28027F, TMS320F28027F-Q1, TMS320F28026 TMS320F28026-Q1, TMS320F28026F, TMS320F28026F-Q1, TMS320F28023 TMS320F28023-Q1, TMS320F28022, TMS320F28021, TMS320F28020, TMS320F280200 SPRS523P – NOVEMBER 2008 – REVISED FEBRUARY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 29 Product Folder Links: TMS320F28027 TMS320F28027-Q1 TMS320F28027F TMS320F28027F-Q1 TMS320F28026 TMS320F28026-Q1 TMS320F28026F TMS320F28026F-Q1 TMS320F28023 TMS320F28023- Q1 TMS320F28022 TMS320F28021 TMS320F28020 TMS320F280200 |
