CSR CSR6027

Radio
 * On-chip baluns for single-ended RF input and output
 * No external trimming required in production
 * Low output spurii and strong receive blocking performance against cellular bands
 * allows for good coexistence with cellular radios


 * Front-end control logic can be programmed to support common 802.11 only and 802.11
 * + Bluetooth RF front-end configurations


 * Support for antenna diversity selection

Transmitter
 * Support for power compensation of external PA to produce stable transmit power across temperature
 * Digital predistortion can be used to compensate for non-linearities in external PA
 * Control of transmit gain settings on a per-packet basis allows transmit power to be optimised
 * for each modulation scheme

Receiver
 * Fast AGC and wide dynamic range allow for excellent robustness against fading

Frequency Synthesiser
 * Fully integrated fractional-N synthesiser
 * Low phase noise and fast switching time
 * Supports all 802.11b/g/n (20MHz) channel frequencies

Frequency Reference
 * Support for common cellular reference frequencies
 * On-chip crystal driver
 * Digital trimming of crystal allows use of less-tightly toleranced crystals
 * Internal low-power clock eliminates requirement foran additional frequency references

Auxiliary Features
 * Four 10-bit ADCs/DACs used for internal calibration. These can also be used to provide
 * a bias voltage or measure the output power of an external PA.
