(*2) contact seiko instruments, inc., (http://www .sii-crystal.com ) for further information about the use of the resonator. (*3) when considering the use of normal xt mode, use an resonator that has a large load capacitance. (*4) when considering the use of low power xt mode, us e a resonator that has a small load capacitance. the applicable cl value of 4.4pf makes it possible to achiev e a high time accuracy for the subclock oscillator as well as high-speed oscillation startup and low power dissipation. in addition to this value, 6.0pf and 7.0pf also fall within the applicable cl value range. (*5) a sample pcb trace pattern for a seiko instrument resonator is shown below. (note 1) the oscillation stabilization time refers to the time interval that is required for the oscillation to get stabilized after an instruction for starting the s ubclock oscillator circuit is issued or the time interval that is required for the oscillation to get stabilized after the hold mode is released (see figure 4). (note 2) the circuit constants shown are the reference values that are provided by the resonator vendor for evaluation. to make final verification of the oscillation characteris tics on production boards, call the resonator vendor for evaluation on printed circuit boards. (note 3) when using an oscillator circuit, observe the following wiring precautions to avoid the possible adverse influence of wiring capacitance, especially in low power xt mode: ? place the components that are involved in oscillation as close to the resonator as possible with the shortest possible traces as the oscillation characteristics ar e subject to the variation of trace patterns. ? do not take a signal directly from the oscillator circuit. ? do not place the oscillator circ uit in the vicinity of any lines that carry large current. ? exercise extreme care in the wiring method when using low power xt mode.
