BCM20740 - Advanced Headset Solution with Fast Charge and Wind Noise Reduction

Advanced Headset Solution with Fast Charge and Wind Noise Reduction

The Broadcom BCM20740 is a monolithic 65 nm, single-chip Bluetooth® 3.0 mono headset solution with very low power consumption. This ROM solution has been designed to permit the lowest possible BOM for low-end mono headsets. The ROM contains a default application built on top of the highly interoperable Broadcom BTE-Audio Stack. Sophisticated configurability has been built into the default application, allowing customers to differentiate. A small patch RAM space is also provided for last minute code changes prior to production.

The BCM20740 transceiver subsystem delivers a highly integrated radio with superior receiver sensitivity. The performance of this subsystem enables greater range and more robust link performance.

The BCM20740 power management subsystem offers the highest level of integration. This subsystem includes the switching regulator, battery charger, LED drivers, and simple battery monitor. The BCM20740 also employs multiple internal LDO regulators for improving isolation, thereby maintaining high radio performance and excellent audio quality.
