Only one external power supply is required for operating the module. DA14580 – 00AT1 XTAL32.768 kHz(optional)XTAL16 MHzAntennaMatching Figure 1: Antenna module block diagram Bluetooth Smart SoC 4.4The DA14580 integrated circuit has a fully integrated radio transceiver and baseband processor for Bluetooth® Smart. It can be used as an application processor as well as a data pump in systems with an external processor. The DA14580 contains an embedded One-Time-Programmable (OTP) memory for storing Bluetooth profiles as well as custom application code. The qualified Bluetooth Smart protocol stack which is stored in a dedicated ROM, and the customer application software which is stored in system RAM, both run on the embedded ARM® Cortex®-M0 processor. Low leakage Retention RAM is used to store sensitive data and connection information while in Deep Sleep mode. The radio transceiver implements the RF part of the Bluetooth Smart protocol. Together with the Bluetooth 4.0 PHY layer, it provides a 93 dB RF link budget for reliable wireless communication. All RF blocks are supplied by on-chip low drop out regulators (LDOs). The RF port is single ended 50 Ω, so no external balun is required. The DA14580 has dedicated hardware for the Link Layer implementation of Bluetooth Smart and interface controllers for enhanced connectivity capabilities. The DA14580 is equipped with a DC/DC converter that can be configured either for buck or boost mode operation. On this module both configurations are available. The default configuration is a buck mode DC/DC converter. Also, the FCC/ETSI certification is valid only for the buck configuration.](https://usermanual.wiki/Dialog-Semiconductor/DA14580REFA/User-Guide-2514497-Page-8.png)

The supply voltage of the module follows the specification of the DA14580 IC in buck configuration. The supply voltage ranges from 2.4 V to 3.6 V. Embedded in the DA14580, the DC/DC converter and LDOs produce all voltages required for the system operation. The DC/DC converter is supplied from VBAT through a bead (FB1) and produces 1.4 V that feeds the internal LDOs. The LDOs supply the digital, analog and RF sections of the chip with 1.2 V. Finally, the I/O ring is supplied from VBAT.

On the QFN48 antenna module the 16 MHz crystal (Y1) has a fundamental frequency of 16 MHz ±10 ppm and a load capacitance of 10 pF. The crystal is located on the module itself. The crystal oscillator frequency can be tuned using a programmable capacitance bank that is embedded in the DA14580. For sleep mode the on-chip RCX oscillator is used (typ. 10 kHz). In addition, a 32.768 kHz crystal (Y2) with a tolerance of ±50 ppm can be mounted on the module.](https://usermanual.wiki/Dialog-Semiconductor/DA14580REFA/User-Guide-2514497-Page-13.png)

Test setup 5.1.2The supply voltage (3.0 V DC) was connected between the PCB pads 27 (VBAT) and 26 (GND). The R&S®CBT Bluetooth® Tester from Rohde & Schwarz was used. Component R5 was removed. The semi-rigid cable was soldered at this pad. See Figure 17. Figure 17: Test setup for the conducted RF measurements Test results 5.1.3The conducted RF sensitivity using a ‘dirty’ transmitter is better than -90 dBm for most channels. Lower sensitivity has been noticed on some channels. This is caused by harmonics of the 16 MHz oscillator.
