STMicroelectronics has released its 4th-generation Bluetooth/FM Radio combo solution, the STLC2690, which is manufactured in ST's advanced low-leakage ultra-low-power 65nm RFCMOS technology. This combination of features and functionality saves space and costs for manufacturers of portable products, while delivering to consumers stereo FM R(B)DS reception (RX) direct to their Bluetooth headsets. The fully integrated short range FM R(B)DS transmitter (TX) allows users to enjoy stored music content on any in-car or home FM radio tuner and delivers increased versatility to the mobile device.
Compliant with BT v2.1+EDR, the STLC2690 increases the field-proven class-1.5 Bluetooth output power, requiring only one supply voltage and without any calibration in production. The Bluetooth link stability is dramatically increased by also further improving the Bluetooth receiver sensitivity, while reducing the current consumption by up to 35 percent compared to former generation products in 130nm technology.
The integrated FM receiver sets a new world standard for receiver sensitivity and with real-time programmable filters for optimum search and sensitivity stability, the STLC2690 can also be used with integrated FM antennas. The device supports all deployed R(B)DS services and all worldwide FM bands (65MHz to 108MHz).
