AMIS-52150
Low-Power Transceiver with Clock and Data Recovery
Data Sheet
1.0 Introduction
The AMIS-52150 is a cost-effective, ultra-low power single-chip wireless transceiver. It combines the proven Amplitude Shift Key/On-Off
Key (ASK/OOK) modulation technology of the AMIS-52050 with data clock recovery.
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.

Data Sheet
8.11 VDD, Supply Voltage Pin
The VDD pin is the power supply pin for the AMIS-52150. 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 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.

Register (HEX) Name

Bits States Comments
All 0xff is highest power
8.13 RFOUT, RF Output Signal Pin
In the AMIS-52150, a high efficiency non-linear output driver is used to produce the high power RF signal. This driver must be
connected through a DC connection to the RFPWR pin. External components are required to match the output to a 50Ω load, or to an
external antenna, respectively.
Figure 6 shows a typical matching circuit for the RFOUT pin.
8.14 RFGND, RF Ground Pin
The RFGND pin is the ground connection for the RF circuits in the device.
