CSR CSR6027

See also: CSR CSR6030 and CSR

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.
