PN17TR 915Mhz Transceiver Module

1 Block Diagram

2 General Description

The PN17TR module is a low power single-chip CC1101 radio transceiver for the 915MHz ISM band. The

transceiver consists of a fully integrated frequency synthesizer, a power amplifier, receiver chain with

demodulator, a crystal oscillator and a modulator. It provides extensive hardware support for packet

handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-

on-radio. The main operating parameters and 64-byte transmit/receive FIFOs of the module can be

controlled via an SPI interface.

Current consumption is very low in receive mode 15.7mA, 1.2kBaud and 200nA sleep mode. Fast start time,

240 µs from sleep to Rx or Tx mode.

The PN17TR module is designed and made for WiLAS series products not for sale on public or other

manufacture host products.

PN17TR 915MHz Transceiver Module 3 Inventis Technology Pty Ltd Transceiver State Diagram After initial setup of registers for desired behavior, the normal operation flow diagram is shown as follows. In applications of infrequent data transmissions the transceiver would be in “sleep” mode to save power (400nA). From there it would be woken up and enter “idle” mode. As part of the wake up process the crystal oscillator is started (~240µS) and the digital microcontroller interface is powered up.
