101 / 306 page  7.10.3 Clock Specifications 7.10.3.1 Clock Sources Table 7-2 lists four possible clock sources. Figure 7-7 provides an overview of the device's clocking system. Table 7-2. Possible Reference Clock Sources CLOCK SOURCE MODULES CLOCKED COMMENTS INTOSC1 Can be used to provide clock for: • Watchdog block • Main PLL • CPU-Timer 2 Internal oscillator 1. Zero-pin overhead 10-MHz internal oscillator. INTOSC2(1) Can be used to provide clock for: • Main PLL • Auxiliary PLL • CPU-Timer 2 Internal oscillator 2. Zero-pin overhead 10-MHz internal oscillator. XTAL Can be used to provide clock for: • Main PLL • Auxiliary PLL • CPU-Timer 2 External crystal or resonator connected between the X1 and X2 pins or single-ended clock connected to the X1 pin. AUXCLKIN Can be used to provide clock for: • Auxiliary PLL • CPU-Timer 2 Single-ended 3.3-V level clock source. GPIO133/AUXCLKIN pin should be used to provide the input clock. (1) On reset, internal oscillator 2 (INTOSC2) is the default clock source for both system PLL (OSCCLK) and auxiliary PLL (AUXOSCCLK). www.ti.com TMS320F28388D, TMS320F28386D, TMS320F28386D-Q1 TMS320F28384D, TMS320F28384D-Q1, TMS320F28388S TMS320F28386S, TMS320F28386S-Q1, TMS320F28384S, TMS320F28384S-Q1 SPRSP14D – MAY 2019 – REVISED FEBRUARY 2021 Copyright © 2021 Texas Instruments Incorporated Submit Document Feedback 101 Product Folder Links: TMS320F28388D TMS320F28386D TMS320F28386D-Q1 TMS320F28384D TMS320F28384D-Q1 TMS320F28388S TMS320F28386S TMS320F28386S-Q1 TMS320F28384S TMS320F28384S-Q1 |
