CC1100 Simplified Block Diagram
A simplified block diagram of
CC1100 is shown
CC1100
features a low-IF receiver. The
received RF signal is amplified by the low-
noise amplifier (LNA) and down-converted in
quadrature (I and Q) to the intermediate
frequency (IF). At IF, the I/Q signals are
digitised by the ADCs. Automatic gain control
(AGC), fine channel filtering, demodulation
bit/packet
synchronization
is
performed
digitally.
The transmitter part of
CC1100 is based on
direct synthesis of the RF frequency. The
frequency synthesizer includes a completely
on-chip LC VCO and a 90 degree phase
shifter for generating the I and Q LO signals to
the down-conversion mixers in receive mode.
A crystal is to be connected to XOSC_Q1 and
XOSC_Q2. The crystal oscillator generates the
reference frequency for the synthesizer, as
well as clocks for the ADC and the digital part.
A 4-wire SPI serial interface is used for
configuration and data buffer access.
The digital baseband includes support for
channel configuration, packet handling and
data buffering.
15 Application Circuit
Only a few external components are required
for using the
CC1100. The recommended
application circuit is shown in Figure 3. The
external components are described in Table
14, and typical values are given in Table 15.
Bias resistor
The bias resistor R171 is used to set an
accurate bias current.
Balun and RF matching
C131, C121, L121 and L131 form a balun that
converts the differential RF port on
CC1100 to a
single-ended RF signal (C124 is also needed
for DC blocking). Together with an appropriate
LC network, the balun components also
transform the impedance to match a 50
antenna (or cable). Component values for the
RF balun and LC network are easily found
using
the
SmartRF
Studio
software.
Suggested values for 315MHz, 433MHz and
868/915MHz are listed in Table 15.
