FX589 - Low-Voltage/High-Speed GMSK Modem

General Description

The FX589 is a single-chip modem employing Gaussian Minimum Shift Keying (GMSK) modulation.

Data rates of 4kb/s to 64kb/s and the choice of BT to 0.3 or 0.5 are pin-programmable functions to suit radio data channel bandwidth requirements.

Key Features

  • Full-Duplex Gaussian Minimum Shift Keying (GMSK) Operating from 3 Volts to 5.5 Volts Data Rates 4kb/s to 64kb/s Selectable BT (0.3 or 0.5) Low-Current Analogue/Digital Non-DSP Solution Meets RCR STD-18.
