DESCRIPTION
CSR7810 offers uniquely voice processing and Bluetooth on a single chip, addressing OEMs’ need for noise reduction in
their products. Users frequently struggle to make themselves heard on a mobile phone, due a multitude of reasons such
as traffic, roadworks and people. In CSR7810 CSR offers both its industry-leading voice processing technology on its
Kalimba DSP and Bluetooth in a small, efficient, cost-effective package.

l 3 Voice processing modes: dual-mic, single-mic and loudspeaker
l CVC 2-mic noise suppression
l Can be used as part of a fully compliant Bluetooth v3.0 + HS system
l Low-power 1.5V operation, 1.8 to 3.6V I/O
l Green (RoHS and no antimony or halogenated flame retardants)
BENEFITS
l CVC 2-mic algorithm for normal handset use
l CVC 1-mic algorithm for use with wired headsets
l CVC hands-free algorithm for effective echo cancellation in loudspeaker mode
l Stationary and dynamic noise removal enabled by dual microphone signal separation in normal handset use
l Removes echo in the outbound speech signal
l Send and receive EQs and AGCs enable an improved user experience allowing compensation for cost driven microphone
