General Description

The DAC1008D650 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 WCDMA transmitters.

Because of its digital on-chip modulation, the DAC1008D650 allows the complex pattern provided through lane 0, lane 1, lane 2 and lane 3, to be converted up from baseband 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

  • Dual 10-bit resolution.
  • 650 Msps maximum update rate.
  • Selectable 2, 4 or 8 interpolation filters.
  • Input data rate up to 312.5 Msps.
  • Very low noise cap free integrated PLL.
  • 32-bit programmable NCO frequency.
  • Four JESD204A serial input lanes.
  • 1.8 V and 3.3 V power supplies.
  • LVDS compatible clock inputs.
  • IMD3: 80 dBc; fs = 640 Msps; fo = 140 MHz.
  • ACPR: 64 dBc; two carriers WCDMA; fs = 640 Msps; fo = 133 MHz.
  • Typical 1.20 W power diss.
