Data Sheet

General Description

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 years

from a small coin cell battery. CSR8811 brings

Bluetooth low energy to the mobile phone, allowing it

to connect to this new class of devices.

CSR8811 is pin-compatible with future CSR chips that

will add support for:

■

Wideband speech

■

On-chip SBC or aptX encoding for streaming

stereo audio with A2DP

It is also pin-compatible with the CSR8810 Bluetooth

v3.0 IC. This makes it easy to upgrade products to the

latest Bluetooth features without changing PCB

design.

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.

Applications

■

Low-cost phones, Feature phones, Smartphones

Personal Navigation Devices (PNDs)

Portable media Players (PMPs)

This family of Bluetooth products that include:

■

CSR8311™ A06 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 single-

ended 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.
