7848 overview
7848 is a component documented by Micronas. The PDF description identifies it as "RDS MODEM / MANCHESTER DECODER." This guide condenses the most useful engineering information from the available PDF so that designers and sourcing teams can identify the checks that still need confirmation in the original document.

Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- On the output the binary data and bit syn- low the threshold’s (VDD + 0,10) / 2V, (VDD - 0.04) /2V chronous clock is available for further frame decoding.
- When the voltage at UTMP drops some analog function blocks such as a FM-tuner volt- below (VDD - 0.04) / 2V the output TMP changes its state age generator, FM comparator, battery voltage and tem- from 1 to 0.
- The power-down circuitry and the 32,768 kHz — oscillator FUNCTIONAL DESCRIPTION semiato : The device is equipment with a power down feature to re- | duce power consumption in pager applications.
- When Manchester decoder the PWR input is high power is cut from all other blocks except for the 32,768 kHz oscillator.
- The circuit accepts an analog 57 kHz signal on its PSK input pin.
- This digital sig- nal is then fed to a 57 kHz PLL.
- The internally generated SL Ly synchronous 57 kHz clock is the used to demodulate the 7 Ea product modulated PSK input signal | The resultant baseband signal is the low pass filtered poe and fedto a 1187,5 Hz PLL.
Topics covered by the datasheet
The document includes sections related to:
- PACKAGE INFORMATION
Engineering review checklist
- Check resistance value, tolerance, temperature coefficient and long-term stability over the operating range.
- Derate continuous power for ambient temperature and verify pulse or surge capability separately.
- Match the land pattern, termination finish and current-sense routing to the exact package option.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
