Notes
1.
Condition for B/G, I and D/K standard: V
CC
= 5 V and
f = 27 kHz (m = 54%). Condition for M standard: V
CC
= 5 V
and
f = 13.5 kHz; 6 dB gain added internally to compensate smaller deviation.
The maximum total system identification time ‘on’ for a channel change is equal to maximum value of t
ident(on)
plus
t
I2C(read-out)
. The maximum total system identification time ‘off’ for a channel change is equal to maximum value of
t
ident(off)
plus t
I2C(read-out)
. The fast mode is proposed mainly during search tuning, program or channel select. If the
channel is selected, the identification response should be switched to normal mode for improved reliability. However
due to the transition from fast to normal mode, the identification bits are not valid for one integrator period. Therefore
the transmitter mode detected during the fast mode has to be stored before changing to normal mode. The storage
has to be kept for two seconds (maximum value of t
ident(on)
in the normal mode) from the moment of transition.
The identification can now operate in the normal mode until the next tuning action.
R modulated and L monitored.
