Product data sheet
8.19.2.1 RDS/RBDS decoder
8.20 Audio pause detector
8.21 Auto search and Preset mode
The RDS decoder provides block synchronization, error correction and flywheel function
for reliable extraction of RDS or RBDS block data. Different modes of operation can be
selected to fit different application requirements. Availability of new data is signalled by bit
DAVFLG and output pin INTX which generates an interrupt. Up to two blocks of data and
status information are available via the I
The behavior of the DAVFLG is described in
The audio pause detector monitors the audio modulation for pauses and responds to low
levels. The modulation threshold can be adjusted in 4 steps of 4 dB by control bits PL[1:0].
The minimum time for detecting a pause can be adjusted by control bits PT[1:0] as shown
in
is generated; see
In Search mode the TEA5764UK can search channels automatically (see
Table
38. When a pause occurs, flag PDFLAG is set to logic 1 and a hardware interrupt
