DAC1005D650
Dual 10-bit DAC, up to 650 Msps; 2× 4× and 8× interpolating
Rev. 2 — 3 September 2010
Product data sheet
1. General description
The DAC1005D650 is a high-speed 10-bit dual-channel Digital-to-Analog Converter
(DAC) with selectable 2×, 4× or 8× interpolating filters optimized for multi-carrier wireless
transmitters.
Thanks to its digital on-chip modulation, the DAC1005D650 allows the complex I and Q
inputs to be converted up from BaseBand (BB) to IF. The mixing frequency is adjusted
using a Serial Peripheral Interface (SPI) with a 32-bit Numerically Controlled Oscillator
(NCO). The phase is controlled by a 16-bit register.
Two modes of operation are available: separate data ports or a single interleaved
high-speed data port. In the Interleaved mode, the input data stream is demultiplexed into
its original I and Q data and then latched.
The DAC1005D650 also includes a 2×, 4× and 8× clock multiplier which provides the
appropriate internal clocks and an internal regulator to adjust the output full-scale current.
