8.9.3.1 Clock Specifications

An external crystal is connected to the device pins. #FIG_D1E247917 shows the crystal implementation.

GUID-B13B09EB-89DD-405F-B5D2-BF03D5A6C86E-low.gifFigure 8-4 Crystal Implementation
Note:

The load capacitors, Cf1 and Cf2 in #FIG_D1E247917, should be chosen such that #T4362547-51 is satisfied. CL in the equation is the load specified by the crystal manufacturer. All discrete components used to implement the oscillator circuit should be placed as close as possible to the associated oscillator CLKP and CLKM pins.Note that Cf1 and Cf2 include the parasitic capacitances due to PCB routing.

Equation 1. GUID-F76D759A-6D15-4C6E-88E2-67E0ACFF1540-low.gif

Table 8-6 lists the electrical characteristics of the clock crystal.

(1) The crystal manufacturer's specification must satisfy this requirement.
(2) Includes initial tolerance of the crystal, drift over temperature, aging and frequency pulling due to incorrect load capacitance.

In the case where an external clock is used as the clock resource, the signal is fed to the CLKP pin only; CLKM is grounded. The phase noise requirement is very important when a 40-MHz clock is fed externally. Table 8-7 lists the electrical characteristics of the external clock signal.
