CLOCK CHARACTERISTICS AND TIMING
The SMJ320C26 can use either its internal oscillator or an external frequency source for a clock.
internal clock option
The internal oscillator is enabled by connecting a crystal across X1 and X2/CLKIN (see Figure 2). The frequency
of CLKOUT1 is one-fourth the crystal fundamental frequency. The crystal should be either fundamental or
overtone mode, and parallel resonant, with an effective series resistance of 30
, a power dissipation of
1 mW, and be specified at a load capacitance of 20 pF. Note that overtone crystals require an additional tuned
LC circuit (see the application report, Hardware Interfacing to the TMS320C25).

external clock option
An external frequency source can be used by injecting the frequency directly into X2/CLKIN with X1 left
unconnected. The external frequency injected must conform to the specifications listed in the table below.
