9.1 I
The TDA18211HD requires a 16 MHz crystal reference. The chosen crystal must
withstand at least 100 W drive level. An additional shunt capacitor as shown in
is also needed. Its typical value is 5.6 pF. The quartz references for which performance is
guaranteed are:
Clock reference:
Pins XTOUTP and XTOUTN deliver a symmetrical sine waveform to drive the channel
decoder and/or IF demodulator. The load on both outputs should be made similar to
ensure optimum performances. Hence, if only one crystal output is used, the unused
output should be loaded by an equivalent capacitance.
Remark: In I
required subaddress 00h. The number of bytes to be read is 16, or 39 in extended register
mode; see
programmed values.

In Master mode, the clock reference must be provided by a 16 MHz crystal connected
between pins XTALP and XTALN of the master tuner
In Slave mode, the clock reference must be provided by pins XTOUTP and XTOUTN
of the tuner in Master mode to pins XTALP and XTALN of the tuner in Slave mode
