MFi Digital Headset Reference Design
The CRD42L42-MFi is a Rapid
Development Platform for Lightning
Connected Headsets
The MFi Headset Reference Design from Cirrus Logic is a
rapid development platform for Lightning^® connected digital
headsets. It uses the CS42L42 codec to enable a hi-fi audio
experience when listening to music or videos or during
a phone conversation. The CS42L42 features a 114 db
headphone D/A converter that can deliver up to 35mW stereo,
and a 114 dB A/D converter with a low noise microphone bias
generator and sidetone mixing to generate clear phone calls.
MCU example code shows how to quickly develop a product
that complies with MFi requirements. The reference design
includes a customer reference design board (CRD) that fits
into a compact pendant form factor and a larger customer
development board (CDB) with header locations for debug.
