Note: It is recommended that the printed circuit board provide a ground plane in the CMX602A area to
provide a low impedance ground connection to the VSS pin and to the bypass capacitors C8 and C9.

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 656k:
@ 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.
