Product specification
Decoder for traffic warning (VWF) radio
transmissions
TDA1579
TDA1579T
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134). All pin numbers in this table apply to
TDA1579; for TDA1579T refer to Fig.1.
CHARACTERISTICS
VP = 8.5 V; Tamb = 25 °C; measured at nominal input signal: ViSK = 8 mV, f = 57 kHz amplitude modulated with
fm = 34.95 Hz and m = 60% for ‘BK-traffic area C’ signal; or with fm = 125 Hz and m = 30% for DK signal.
All pin numbers in this table apply to TDA1579, for TDA1579T refer to Fig.1.
