AMIS-52100 Low-Power Transceiver with Clock and Data Recovery
Data Sheet
1.0 Introduction
The AMIS-52100 is a low-cost, ultra-low power single chip transceiver. It combines the proven amplitude shift key/on-off key
(ASK/OOK) modulation technology of the AMIS-52000 with data clock recovery. The AMIS-52100 is targeted at narrow band
applications in the 402 to 405MHz range.
Features such as dual independent receive channels, quick start crystal oscillator start up, Sniff Mode™ signal acquisition, and data
clock recovery make the AMIS-52100 ideally suited for a wide range of customer applications. Applications that the AMIS-52100 can be
used for are point-to-point wireless data links, low cost wireless monitors, very low power remote wireless sensors, and many other
uses.

Data Sheet
8.11 VDD, Supply Voltage
The VDD pin is the power supply pin for the AMIS-52100. The voltage on this pin is typically 3.0V. Please refer to the section
“Operating and Maximum Specifications” of this document for the VDD operating conditions.
8.12 RFPWR, DC Voltage Output
The AMIS-52100 generates a regulated DC voltage that is output on the RFPWR pin. This voltage should be fed through a DC
connection to the RFOUT pin to power the output stage of the RF PA. The AMIS-52100 adjusts the voltage level through the value of
the register shown in
Table 19.

8.13 RFOUT, RF Output Signal
The AMIS-52100 uses a high efficiency non-linear output driver to produce the high power RF signal. This final driver must be
connected through a DC connection to the RFPWR pin of the AMIS-52100. External components are required to match the output to a
50Ωload or to an external antenna. Figure 6 shows a typical matching circuit for the RFOUT pin.
8.14 RFGND, RF Ground
The RFGND pin is the ground connection for the RF circuits in the AMIS-52100.
