The programmable module address bits MA[1:0] allow up to four tuners to be addressed
in one system. Bits MA[1:0] are programmed by applying a specific voltage (V
AS. The relationship between the status of bits MA[1:0] and the voltage applied to pin AS
is shown in
Table 5.
Legend: * power-on reset value.
Example: MA[1:0] = 00, R/W = 0, full module address = 1100 0000 (C0h).

TDA18218HN embeds a Xtal oscillator and a buffer to drive another IC. The buffer can be
configured through register XTOUT (I
designed to be AC coupled. This output can be used in differential or sinusoidal mode
(using XTO_N and XTO_P pins) or in asymmetrical or square mode (just leaving one pin
open).
It should be noted that TDA18218HN specification refers to differential output with no
load.
