TEA1069; TEA1069A
The DC-level at the TONE output measures

V
DD
and the impedance is typically 100
. DTMF frequencies are
composed by transmitting 2 tones simultaneously at pin TONE. The frequency tolerance for the tones at output TONE
is shown in Table 4.

t
t
= burst time.
t
p
= pause time.
t
holdover
= hold-over time.
t
rc
= recall time.
t
interflash
= interflash hold-over time (only for TEA1069A).
Note: in case of manual dialling only the minimum tone burst and pause time values depend on the chosen diode option, the maximum tone burst/pause
times are equal to the real key press/release time.
