March 26, 2015 – Analog Devices (www.analog.com, NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, has released the AD9154, a quad-channel, 2.4 GSPS, 16-bit D/A converter. This product provides industry-leading dynamic range for Complex IF (intermediate frequency) transmitters in the 100–300 MHz band. The highly integrated AD9154 quad, 16-bit D/A converter is the only product in its class to include an on-chip Phase-Locked Loop (PLL) and an 8-lane JESD204B interface. These features allow designers to meet the requirements of multi-frequency GSM and LTE transmitters designed for wireless macro base stations, P2P micro radio, military radio, and wireless test equipment using a single device. The newly released converter includes specifications optimized for Complex IF transmission applications, such as Complex digital modulation, input signal power sensing, gain, phase, and offset compensation.

The AD9154 quad, 2.4GSPS, 16-bit D/A converter is designed to up-convert a pair of I/Q digital input signals to generate a Complex IF signal from a pair of on-chip D/A converter cores. This product supports several interpolation modes, allowing the digital signal sampling rate to be raised to the Nyquist frequency, which enables a simpler and more cost-effective implementation of the transmit filter for the analog output of the D/A converter. Additionally, it features a digital signal correction function to eliminate RF local leakage or unwanted side-band components generated by the Quadrature Modulator Up Converter.

The AD9154 converter is designed to use an 8-lane JESD204B interface. The JESD204B interface provides deterministic delay and multiple device synchronization to radio transmitters using multiple antennas, a growing common feature in radio base stations, radar, and military radio communications, in order to simplify board layout.

The AD9154 quad, 16-bit D/A converter extends ADI’s transmission capability to the 100–300 MHz range, and other products include the AD9144 quad, 16-bit D/A converter operating in the DC–100 MHz range and the 16-bit dual-channel D/A converter scheduled for subsequent release.
