Functional Block Diagram
The AMIS-52150 is a dual-channel receiver and a transmitter in a single, small outline package (Fig. 1). The receiver provides for two
independent receive channels with the signals combined in the data detection circuit. Summing the signals allows the two channels to
be used for antenna diversity optimization, without the need for complex protocols to select the strongest channel. The AMIS-52150 can
be programmed to be a single channel or a dual-channel receiver, respectively. There exist internal trim functions for the RF receiver
frequency, for tuning each input port, for setting the internal filters to match the data rate, and for setting the threshold level for acquiring
an incoming signal, respectively. The receiver converts the received RF signal to a low frequency IF. An RSSI circuit determines the
strength of the received signal. A level detector samples the RSSI signal level and compares that level to the slice threshold to recover
the data. The slice threshold can be either set to a fixed level, or alternately, the transceiver can be configured to automatically set the
threshold level based on the incoming data.
The transmitter is a high efficiency power amplifier (PA) that is turned On or Off by the serial data. The output power level is adjustable.
The frequency of the RF output can be tuned with an internal crystal trim function, in order to conform to component and manufacturing
tolerances. 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
external microcontroller wake up the device, respectively. The receiver can be also configured for operation in Sniff Mode
, where by
the device is programmed to wake up at regular intervals to sniff for received 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. This feature enables reducing much of
the jitter in the data signal.
These functions will be described in more detail later in the document.
