DAC38RF86 (ACTIVE)

Dual-Channel, 14-Bit, 9-GSPS, 6x-24x Interpolating, 9 GHz GSM PLL Digital-to-Analog Converter (DAC)

 

Description

The DAC38RF86/96 is a family of high-performance, dual-channel, 14-bit, 9-GSPS, RF-sampling digital-to-analog converters (DACs) that are capable of synthesizing wideband signals from 0 to 4.5 GHz. The DAC38RF87/97 is also a family of high-performance, dual-channel, 14-bit, 6-GSPS, RF-sampling digital-to-analog converters (DACs) that are capable of synthesizing wideband signals from 0 to 3 GHz. A high dynamic range allows the DAC38RFxx family to generate signals for a wide range of applications including 3G/4G signals for wireless base-stations and radar.

The devices feature a low-power JESD204B Interface with up to 8 lanes with a maximum bit rate of 12.5 Gbps allowing an input data rate of 1.25 GSPS complex per channel. The DAC38RFxx provides two digital up-converters per channel, with multiple options for interpolation rates. A digital quadrature modulator with independent, frequency flexible NCOs are available to support multi-band operation. A GSM compliant low phase noise PLL/VCO is integrated to simplify the DAC sampling clock generation by allowing the use of a lower frequency reference clock
