69 / 226 page ![]() 8.9.3.5 Internal Oscillators To reduce production board costs and application development time, all F2837xD devices contain two independent internal oscillators, referred to as INTOSC1 and INTOSC2. By default, both oscillators are enabled at power up. INTOSC2 is set as the source for the system reference clock (OSCCLK) and INTOSC1 is set as the backup clock source. INTOSC1 can also be manually configured as the system reference clock (OSCCLK). Section 8.9.3.5.1 provides the electrical characteristics of the internal oscillators to determine if this module meets the clocking requirements of the application. Section 8.9.3.5.1 provides the electrical characteristics of the two internal oscillators. Note This oscillator cannot be used as the PLL source if the PLLSYSCLK is configured to frequencies above 194 MHz. 8.9.3.5.1 Internal Oscillator Electrical Characteristics over recommended operating conditions (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP MAX UNIT f(INTOSC) Frequency, INTOSC1 and INTOSC2 9.7 10.0 10.3 MHz f(INTOSC-STABILITY) Frequency stability at room temperature 30°C, Nominal VDD ±0.1% Frequency stability over VDD 30°C ±0.2% Frequency stability –3.0% 3.0% f(INTOSC-ST) Start-up and settling time 20 µs 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 69 Product Folder Links: TMS320F28379D TMS320F28379D-Q1 TMS320F28378D TMS320F28377D TMS320F28377D-Q1 TMS320F28376D TMS320F28375D TMS320F28374D |
