Figure 2: Recommended External Components
Notes:
1. Xtal/clock components described are recommended in accordance with MX-COM's Application Note on Standard and
DBS 800 Crystal Oscillator Circuits (April 1990). For best results, a crystal oscillator design should drive the clock
inverter input with signal levels of at least 40% of V
DD
, peak to peak. Tuning fork crystals generally cannot meet this
requirement. To obtain crystal oscillator design assistance, consult your crystal manufacturer.
2. System Components whose values are calculated to allow the MX803A to operate with other DBS 800 microcircuits.
Figure 3 shows these components used in the system signal paths.
3. R3, R4, R5 and C5 are tone mixing components calculated to provide a 3dB tone differential (twist) for use in a DTMF
configuration. Single tone output levels are set independently.
4. When X1 > 5.00MHz, C3 = C4 = 18pF
5. R7 provides modulation level and matching outputs for the MX803A.
