Figure 3. EM260 Block Diagram
The radio receiver is a low-IF, super-heterodyne receiver. It utilizes differential signal paths to minimize noise
interference, and its architecture has been chosen to optimize co-existence with other devices within the
2.4GHz band (namely, IEEE 802.11g and Bluetooth). After amplification and mixing, the signal is filtered and
combined prior to being sampled by an ADC.
The digital receiver implements a coherent demodulator to generate a chip stream for the hardware-based
MAC. In addition, the digital receiver contains the analog radio calibration routines and control of the gain
within the receiver path.
The radio transmitter utilizes an efficient architecture in which the data stream directly modulates the VCO.
An integrated PA boosts the output power. The calibration of the TX path as well as the output power is
controlled by digital logic. If the EM260 is to be used with an external PA, the TX_ACTIVE signal should be used
to control the timing of the external switching logic.
The integrated 4.8 GHz VCO and loop filter minimize off-chip circuitry. Only a 24MHz crystal with its loading
capacitors is required to properly establish the PLL reference signal.
