1 / 18 page  1 PRODUCT INFORMATION CML Semiconductor Products FX589 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 Applications Wireless LAN/Modems Handy Data Terminals Low-Power Wireless Data Link for PCs, Laptops and Printers Point-Of-Sale Terminals Wireless Bar-Code Readers and Stock Controllers Brief 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. The Rx and Tx digital data interfaces are bit-serial and synchronised to Rx and Tx data clocks generated by the modem. Separate Rx and Tx Powersave/Enable inputs allow for full- or half-duplex operation. Rx input levels can be set by a suitable ac and dc level adjusting circuit built, with external components, around an on-chip Rx input amplifier.

Indication is available, from the Rx S/N output, as to the quality of the received signal. The FX589 design features a low-current analogue/digital ASIC process offering significantly lower current consumption than DSP technology. For data rates up to 32kb/s the FX589 draws typically 1.5mA at 3.0 volts V DD and for data rates up to 64kb/s at 5.0 volts, typically 4.0mA. This low-power CMOS microcircuit is available in both 24-pin plastic DIL and Small Outline (SOIC and SSOP) packages. Publication D/589/7 January 1998 |
