If a crystal is used as the clocking source, connect it to both the Ref_in (pin 47) and Ref_out (pin 46) pins
of the ICS1893BF. A pair of bypass capacitors on either side of the crystal are connected to ground. The
crystal is used in the parallel resonance or anti-resonance mode. The value of the bypass caps serve to
adjust the final frequency of the crystal oscillation. Typical applications would use 33pF bypass caps. The
exact value will be affected by the board routing capacitance on Ref_in and Ref_out pins. Smaller bypass
capacitors raise the frequency of oscillation. Once the exact value of bypass capacitance is established it
will be the same for all boards using the same specification crystal. The best way to measure the crystal
frequency is to measure the frequency of TXCLK (pin 37) using a frequency counter with a 10 second
sample. Using TXCLK prevents affecting the crystal frequency by the measurement. The crystal
specification is shown in Table 5.1.
