CSR8811A08 Product Details

The CSR8811™ is a product from CSR's Connectivity Centre. It is a single-chip radio and baseband IC for Bluetooth 2.4GHz systems including EDR to 3Mbits/s and Bluetooth low energy.
CSR8811's dual-mode radio enables it to connect to the billions of Bluetooth products already on the market, as well as a new generation of Bluetooth low energy devices.
Bluetooth low energy allows mobile devices to exchange simple data sets with very low consumption.Example use cases include watches, medical sensors and fitness trainers that can operate for many yearsfrom a small coin cell battery. CSR8811 brings Bluetooth low energy to the mobile phone, allowing it to connect to this new class of devices.
When used with CSR Synergy Software™ and a CSR UniFi ® wireless chip, CSR8811 provides a system fully qualifiable to the Bluetooth v4.0 + HS system for faster file transfer.
This family of Bluetooth products includes:
■ CSR8311™ A08 for automotive applications
■ CSR8510™ A06 for PCs and USB dongles

Products requiring a standalone Bluetooth low energy radio should use CSR1000™ or CSR1001™ ICs.

CSR designed CSR8811 to reduce PCB area and the number of external components:

■ The high-power Class 1 Bluetooth transmitter removes the requirement for external amplification. 

■ The balun is integrated, which results in a singleended 50Ω port that does not require additional matching components. 

■ Integrated LDOs, with minimum decoupling components, allow the chip to be operated directly from the battery or a regulated supply.

■ No requirement for external inductors. This ensures that production costs are minimised. The device incorporates auto-calibration and BIST routines to simplify development, type approval and production test. To improve the performance of both Bluetooth and IEEE 802.11b/g/n co-located systems a wide range of coexistence features are supported.
