ML7037 – Dual Echo Canceller & Noise Canceller for Handsfree Systems

The new ML7037 enables full-duplex handsfree conversation using the latest echo and noise cancellation technology plus a dual codec in a single-chip solution. The device targets applications like speaker-phones, handsfree car kits, video-conferencing and intercom systems.

Additionally to the analog interface, the ML7037 also incorporates a digital PCM interface on the line-side. The device can be used in standalone or MCU control mode, which increases the flexibility to match any system architecture. The new echo cancelling algorithm cancels echos of up to 100ms delay attenuating them
at 35dB. Its outstanding characteristics together with a wide range of variable parameters make the ML7037 a state-of-the-art solution.

The ML7037 Eva Kit is available for customer evaluation of this device.
