8.4Oscillator Electrical Specifications

The applications processor contains two oscillators – 32.768 kHz and 3.6864 MHz; each chosen for a specific crystal. When choosing a crystal, match the crystal parameters as closely as possible.

8.4.132.768 kHz Oscillator Specifications

The 32.768 kHz Oscillator is connected between the TXTAL (amplifier input) and TEXTAL (amplified output). The 32.768 kHz specifications are shown in Table 8-4.
