OL2381AHN/C0B,515 General Description

A highly integrated single-chip transceiver solution, the OL2381 is ideally suited totelemetry applications operating in the ISM/SRD bands. The small form factor, low powerconsumption and wide supply voltage range make this device suitable for use in batterypowered, handheld devices and their counter parts.The device utilizes a fully integrated, programmable fractional-N PLL (including loop filter)to control the Local Oscillator (LO), thus supporting multi-channel operation andfrequency hopping schemes. This feature also allows programmable frequency steps forcrystal (XTAL) drift compensation.The device can employ ASK, FSK or GFSK type modulation. The ASK modulationcharacteristics are fully programmable by varying the power amplifier output power inaccordance with the TX data. The FSK modulation utilizes the fractional-N PLL capabilityto precisely modulate the LO frequency with the TX data (in loop modulation). Relaxednarrow band applications can utilize an on-chip GFSK type modulation to improve thespectral occupancy.The device is based on a low IF direct conversion receiver architecture, with on-chip IFfiltering and programmable channel bandwidth. After filtering and amplification thequadrature signals are digitized, demodulated and processed in the digital domain.Baseband processing of the received signal comprises a demodulator, a data-slicer andclock recovery followed by a Manchester decoder. Automated signal signature recognitionunits are available to allow simple, fast and reliable data reception.The device is controlled via a three-wire serial interface (SPI) with data input and output,data clock and interface enable. The interface can be configured to a full SPI interfacewith separate data and clock pins. Additional pins are available to access internal signalsin real-time.
