Table 8-4. 32.768 kHz Oscillator Specifications (Sheet 2 of 2)

Symbol	Description	Min	Typical	Max

tS_XT	Stabilization Time	2 s	—	10 s
Board Specifications

RP_XT	Parasitic Resistance, TXTAL/TEXTAL to any node	20 MΩ	—	—
CP_XT	Parasitic Capacitance, TXTAL/TEXTAL, total	—	—	5 pF
COP_XT	Parasitic Shunt Capacitance, TXTAL to TEXTAL	—	—	0.4 pF

To drive the 32.768 kHz crystal pins from an external source:

•Drive the TEXTAL pin with a digital signal that has a low level near 0 V and a high level near VCC. Do not exceed VCC or go below VSS by more than 100 mV. The minimum slew rate is 1V per ∝s. The maximum current drawn by the external clock source when the clock is at its maximum positive voltage should be about 1mA.

•Float the TXTAL pin or drive it complementary to the TEXTAL pin, using the same voltage level, slew rate, and input current restrictions.

8.4.23.6864 MHz Oscillator Specifications

The 3.6864 MHz Oscillator is connected between the PXTAL (amplifier input) and PEXTAL (amplified output). The 3.6864 MHz specifications are shown in Table 8-5
