fundamental cut crystals or third overtone mode crystals, parallel resonant. If sin-
gle-ended oscillators are used they must be connected to XT0I and XT1I. The
clock source options and circuit requirements are shown in Figure 26.
es that output CMOS voltage levels are required. The load capacitance in the crys-
tal configurations may vary depending on the magnitude of board parasitic
capacitance. The Bt848 is dynamic, and, to ensure proper operation, the clocks
must always be running, with a minimum frequency of 28.636363 MHz.
Crystals are specified as follows:
The following crystals are recommended for use with the Bt848:
The two clock sources may be configured with either single-ended oscillators,
The clock source tolerance should be 50 parts-per-million (ppm) or less. Devic-
