DAC1208D750HN-C18

Digital To Analog Converters Overview

The DAC1208D750HN-C18 is a high-speed dual-channel 12-bit Digital-to-Analog Converter (DAC) manufactured by Renesas Electronics Corporation. It features selectable 2x, 4x, or 8x interpolating filters and supports up to 750 Msps maximum update rate with input data rates up to 312.5 Msps. The device utilizes a JESD204A serial interface with four lanes supporting up to 3.125 Gbps per lane. It includes an embedded complex modulator with a 32-bit Numerically Controlled Oscillator (NCO) for frequency translation from baseband to IF. Power supplies are 1.8 V for digital/analog logic and 3.3 V for analog circuits. The component operates within an industrial temperature range of -40 °C to +85 °C and is housed in a 64-terminal HVQFN package.

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Renesas Electronics Corporation against the original Integrated Device Technology (IDT) datasheet documentation. Confirm that the C18 suffix corresponds to the specific industrial temperature grade (-40 °C to +85 °C) and packaging variant listed in official ordering information. Ensure compatibility with JESD204A standards and required power supply voltages during acquisition.

Digital To Analog Converters Selection Notes

Select this component for applications requiring high-speed dual-channel conversion with integrated interpolation and modulation. Verify system requirements for 1.8 V and 3.3 V power supplies and LVDS clock inputs. Consider the thermal resistance characteristics and the necessity of a heatsink due to the exposed die pad design. Ensure FPGA or SERDES interfaces support the JESD204A protocol and lane configurations.

Digital To Analog Converters Part Context

This component belongs to the DAC1208D750 series of high-speed interpolating DACs originally developed by Integrated Device Technology (IDT). The series is characterized by its integration of digital signal processing functions such as interpolation filtering and quadrature modulation directly within the DAC architecture. This integration reduces the complexity of external digital logic required for multi-carrier transmitter designs.

Digital To Analog Converters Replacement Considerations

Check for other variants within the DAC1208D750 family, such as those with different suffixes indicating package or temperature variations. Verify pinout and register compatibility before substituting with other dual-channel high-speed DACs from Renesas or IDT product lines.
