DAC12DL3200ALJ

Digital To Analog Converters Overview

The DAC12DL3200ALJ is a dual-channel, 12-bit RF sampling digital-to-analog converter (DAC) manufactured by Texas Instruments. It supports input and output rates up to 3.2 GSPS in dual channel mode or 6.4 GSPS in single channel mode. The device features low latency of 6 to 8 ns through the device, matching transmit capabilities with the ADC12DL3200 receiver. It utilizes a parallel LVDS interface with up to 48 LVDS pairs and 4 DDR LVDS clocks, supporting multi-Nyquist operating modes including NRZ, RTZ, RF, and 2xRF. The DAC includes an on-chip direct digital synthesizer (DDS) for single-tone and two-tone generation. Power supplies required are 1.0 V, 1.8 V, and –1.8 V, with power consumption at 1.49 W in dual channel RF mode at 3.2 GSPS. The component is housed in a 256-ball FCBGA package measuring 17 mm x 17 mm.

Digital To Analog Converters Procurement Notes

Verify the specific ALJ suffix against the manufacturer's orderable addendum to confirm package type and temperature range specifications. Ensure compatibility with JESD204B/C clocking devices when designing multi-device synchronization architectures. Confirm that the 256-ball FCBGA footprint matches the target PCB layout requirements before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed RF sampling with minimal processing delay. The device is suitable for I/Q baseband conversion in dual channel mode. Consider the 21 mA full-scale current and 1.0 V, 1.8 V, –1.8 V supply requirements during power budget planning. Evaluate the need for external DDS functionality versus utilizing the integrated NCO blocks for tone generation.
