TDA1579 Description

Short technical summary and product information.

The TDA1579 from NXP Semiconductors is an integrated circuit decoder specifically designed for radio transmissions utilizing 57 kHz amplitude-modulated subcarriers, as employed in the German 'Verkehrs Warnfunk' (VWF) traffic warning system.

Key features include a selective subcarrier amplifier with gain control, a transmitter identification signal (SK) decoder, and active filtering for area identification signal (BK) and announcement identification signal (DK). The device incorporates BK and DK decoders with switched hysteresis, along with switch-on/switch-off delay circuits for these signals. It also provides a driver output for an SK indicator (LED) and control outputs for SK and BK signals.

This decoder operates within a supply voltage range of 7.5V to 12V and has a typical supply current of 6mA. The nominal input voltage at 57 kHz is 8mV, with an input impedance of 100 kΩ. The operating ambient temperature range is -30°C to +80°C.

The TDA1579 is available in an 18-lead DIL plastic package (SOT102). Its applications are centered around receiving and decoding traffic warning radio transmissions.
