The new converters have a maximum sample rate of 2.8 GSPS, which allows multicarrier generation up to the Nyquist frequency.
The converters 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. The new devices achieve better than -80dBc spurious-free dynamic range (SFDR) and have exceptional noise performance of -163dBm/Hz that provide high quality synthesis of wideband signals.
The speed and noise performance results in faster, cleaner data transmission and reduces infrastructure costs by allowing wireless carriers to space point-to-point microwave repeaters farther apart.
The 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 new converters also include integrated interpolation filters with selectable interpolation factors of 1, 2, 4, and 8.
