Figure 2 : Recommended External Components for Dual Bellcore and British Telecom Application
Recommended External Component Notes:
1. See section 4.8
2. See section 4.2
3. The recommended values of R8 were selected for applications in both Bellcore and British Telecom Systems.
Optimum Bellcore-only operation may be achieved by reducing the value of R8 e.g. to 656kΩ @ 5.0V.
4. For best results, a crystal oscillator design should drive the clock inverter input with signal levels of at least 40% of
VDD, peak to peak. Tuning fork crystals generally cannot meet this requirement. To obtain crystal oscillator design
assistance, consult your crystal manufacturer.
