DAC1405D750 Datasheet Dual 14-bit Dac

Manufacturer: NXP Semiconductors

Overview: DAC1405D750 Rev. 01 — 10 March 2010 .. Dual 14-bit DAC, up to 750 Msps; 4× and 8× interpolating Preliminary data sheet 1.

General Description

The DAC1405D750 is a high-speed 14-bit dual channel Digital-to-Analog Converter (DAC) with selectable 4× or 8× interpolating filters optimized for multi-carrier wireless transmitters.

Thanks to its digital on-chip modulation, the DAC1405D750 allows the plex I and Q inputs to be converted from BaseBand (BB) to IF.

The mixing frequency is adjusted via a Serial Peripheral Interface (SPI) with a 32-bit Numerically Controlled Oscillator (NCO) and the phase is controlled by a 16-bit register.

Key Features
