Crystal Oscillator
The MT88E43 requires a 3.579545MHz crystal oscillator as the master timing source.
The crystal specification is as follows:
Frequency:
Frequency tolerance:
Resonance mode:
Load capacitance:
Maximum series resistance: 150 ohms
Maximum drive level (mW): 2 mW
e.g., CTS MP036S
Any number of MT88E43 devices can be connected as shown in Figure 8 such that only one crystal is required.
The connection between OSC2 and OSC1
can be D.C. coupled as shown, or the OSC1 input on all devices can be driven from a CMOS buffer (dc coupled)
with the OSC2 outputs left unconnected.
To meet BT and Bellcore requirements for proper tone detection the crystal must have a frequency tolerance of
0.1%.
