Dual D-A converters

19 November 2014 Analogue, Mixed Signal, LSI

Analog Devices introduced a 2,8 GSps dual 16-bit converter for telecommunications system manufacturers that require microwave frequencies in point-to-point wireless backhaul equipment. The 16-bit AD9136 and 11-bit AD9135 dual D-A converters achieve exceptional signal bandwidth while enabling designers to support emerging E-band (71 - 76 GHz and 81 - 86 GHz) frequencies being adopted by wireless carriers to support steadily increasing demand for high-speed mobile voice and data transfers.

The devices support complex input data rates of up to 2,12 GSps per D-A converter using a flexible, 8-lane, 10,6 Gbps JESD204B interface. They achieve better than -80 dBc spurious-free dynamic range (SFDR) and have exceptional noise performance of -163 dBm/Hz that provide high quality synthesis of wideband signals.

The AD9136/5 converters require only 1,4 W of power under full operating conditions and integrate a low-noise PLL (phase-locked loop), which lowers bill of materials costs and simplifies system design by eliminating the need for a high-performance source clock. The ICs also include integrated interpolation filters with selectable interpolation factors of 1, 2, 4 and 8.

In a point-to-point radio system design, the AD9136/5 are optimised to interface seamlessly with Analog Devices’ ADRF672x analog quadrature modulators.
