... Based on key features, such as dual independent receive channels, Quick Start crystal oscillator, Sniff Mode™ signal acquisition, and data clock recovery, the AMIS-52150 is ideally suited for a wide range of applications, including point-to-point wireless data links, cost- optimized wireless monitor solutions, and very low power remote wireless sensors, among others. ...

... In addition, the design of the transceiver is based on a number of unique features. The AMIS-52150 can be placed in a very low power state, with the crystal oscillator being Off while the low power RC oscillator maintains the chip operation. In this low power state, the AMIS-52150 remains in the sleep mode until either the wake-up timer or an ...

... RF signals, returning to the sleep mode if a signal is not detected. The AMIS-52150 contains a Quick Start circuit as well, which results in full operation of the crystal oscillator in an extremely short time, in turn leading to much lower power consumption as compared to other transceiver products available in the market. In the AMIS-52150, a programmable PLL is used to synchronize the data clock to the received data ...

... RX1, RX2, RF Input Pins RX1 and RX2 are the RF antenna inputs to the AMIS-52150. The internal circuit designs are identical between these inputs. For the AMIS-52150 receiver inputs, RX1 and RX2, external components are required in order to match the low noise amplifier (LNA) to external devices such as antennas. The external components must provide a DC voltage path to the RF ground. Figure 3 suggests an external circuit for the receiver inputs at 403MHz. Each circuit’ ...

... VCO1, VCO2, Voltage Controlled Oscillator Pins The VCO1 and VCO2 pins connect a parallel combination of a capacitor and an inductor to the AMIS-52150 internal voltage controlled oscillator (VCO). The external LC (parallel inductor and capacitor) circuit sets the frequency of the internal VCO. The VCO frequency must be set to twice the value of the desired frequency ...

... The LPFILT pin connects the AMIS-52150 internal phase lock loop (PLL) frequency synthesizer to an external loop filter (Fig. 5). An external loop filter allows the system designer to optimize the operation of the AMIS-52150 in order to meet the requirements for a specific end application. For further details, refer to the application note titled “Extending to Frequencies Outside of the 403MHz Target” ...

... AMIS-52150 8.12 RFPWR, DC Voltage Output Pin In the AMIS-52150, a regulated DC voltage is generated and outputted at the RFPWR pin. This voltage should be fed through a DC connection to the RFOUT pin in order to power the output stage of the RF PA. The voltage level is adjusted based on the value of the register setting, as shown in Table 19 ...

... The different phases of the reflected signals cause the signal strength at the receiver to vary. This variation can be large enough to cause the receiver to miss information. The AMIS-52150 sums the signals from the dual receiver channels within the data detection circuits. This reduces the effect of multi-path reflections. Proper operation requires a) trimming aimed at minimizing the frequency tolerances, b)tuning of the oscillator frequency, c)selection of the data rate filters, and d)setting of a signal threshold, as shown in Table 20 ...

... The crystal oscillator provides the reference frequency which is used to generate the RF frequencies for transmission and receiving of data also the reference for all the timing functions in the AMIS-52150. The RC oscillator is in turn used to produce a “kicker” signal when the Quick Start function of the crystal oscillator is needed. ...

... The RSSI circuit creates an analog voltage waveform (18mV/dB) that follows the signal strength of the RF signal. The data slice circuit then samples that waveform to create the digitized data. The slice circuit in the AMIS-52150 can be programmed to operate in one of three modes; DAC mode, Average mode or Peak mode. The DAC mode compares a fixed slice threshold value to the level in the slice output. The digital data state is determined by the level of the slice output being above or below that fixed threshold. For further details, refer to the application note titled “ ...
