Description
TIDC-DSSS868WMBUS-DC enables data collectors with optimized firmware for receiving wireless M-Bus (wM-Bus) packets in frequent transmission (T-) and compact (C-) modes at 868.95 MHz. For improved range, a customized direct sequence spread spectrum (DSSS)-coded packet reception is also supported. This reference design can be adapted for wM-Bus and DSSS-enabled data collectors and mobile readers at 169-MHz and 433-MHz bands.
Features
- Battery-powered data collector (or Mobile reader) for wM-Bus T- and C-mode or DSSS-coded data packets
- 10 Vin ultra-low Iq DC/DC supports multiple battery types, configurations and chemistries.
- Market leading blocking, selectivity and RX sensitivity in wM-Bus T-mode with +-12% data rate variation with 100 kcps @ 868.95 MHz for a robust wireless design
- EN13757-4 T- and C-mode compliant "other" device with open source code examples for receive operation
- 11-bits (and 16-bits) DSSS-coding of data supported in hardware
- This ultra low-power, battery-operated data collector system is tested and includes open source licensed firmware. It also includes SRF7 studio GUI configuration files and user's guide and our sub-1 GHz transceiver, MSP430 microcontroller and ultra-low Iq step--down converter.
