PRODUCTION DATA. DAC38RF82, DAC38RF89 SLASEA6B – FEBRUARY 2017 – REVISED AUGUST 2017 DAC38RF8x Dual-Channel, Differential-Output, 14-Bit, 9-GSPS, RF-Sampling DAC With JESD204B Interface, On-Chip PLL and Wide-Band Interpolation 1 1 Features 1 • 14-Bit Resolution, 9-GSPS DAC with Multimode Operation – 16-Bit, Dual-Channel Data Mode – Max Input Rate: 2.5-GSPS – Wideband Digital Up-converter – Interpolation: 1,2,4,6,8,10,12,16,18,20,24x – 12-Bit, Dual-Channel Data Mode – Max Input Rate: 3.33-GSPS – Wideband Digital Up-converter – Interpolation: 1,2,24x – 8-Bit, Single-Channel Data Mode – Max Input Rate: 9-GSPS • JESD204B Interface – Subclass 1 for Multichip Synchronization – Maximum Lane Rate: 12.5 Gbps • Differential Output – Supports DC Coupling – RF Full-Scale Output Power (with 2:1 Balun): 3 dBm at 2.14 GHz • Internal PLL and VCO with bypass – DAC38RF82: fC(VCO) = 5.9 or 8.9 GHz – DAC38RF89: fC(VCO) = 5 or 7.5 GHz • Power Supplies: -1.8 V, 1.0 V, 1.8 V • Package: 10 x 10 mm BGA, 0.8mm Pitch, 144-Balls 2 Applications • Arbitrary Waveform Generators • Radar and Electronic Warfare • Communications Test Equipment • Direct RF Synthesis for DOCSIS 3.0/3.1 • Microwave Backhaul 3 Description The DAC38RF82 and DAC38RF89 are high performance, wide bandwidth RF-sampling digital-to- analog (DACs) that are capable of dual channel input data rate up to 3.33 GSPS or single-channel operation with 8-bits up to 9-GSPS. The devices have a low power JESD204B Interface with up to 8 lanes, with a maximum bit rate of 12.5 Gbps. In dual channel operation, the input interface is capable of data rates up to 3.33 GSPS at 12-bits and 2.5 GSPS at 16-bits resolution without interpolation. When used as a complex baseband transmitter with interpolation modes from 2x to 24x, the DAC38RF82 or DAC38RF89 is capable of synthesizing wideband signals up to 2 GHz bandwidth with 16-bit input resolution and 2.66 GHz bandwidth with 12-bit input resolution. The 8-bit mode allows an input at the full 9 GSPS maximum DAC sample rate and can synthesize wideband signals from 0 to 4.5 GHz. An optional low jitter PLL/VCO simplifies the DAC clock generation by allowing use of a lower frequency reference clock. DAC38RF82 and DAC38RF89 support different VCO frequency ranges, summarized in Device Comparison Table.
