The AFE7070 is a dual 14-bit 65-MSPS digital-to-analog converter (DAC) with integrated,
programmable fourth-order baseband filter and analog quadrature modulator. The AFE7070 includes
additional digital signal-processing features such as a numerically controlled oscillator for
frequency generation/translation, and a quadrature modulator correction circuit, providing LO and
sideband suppression capability. The AFE7070 has an interleaved 14-bit 1.8-V to 3.3-V CMOS input.
The AFE7070 provides 20 MHz of RF signal bandwidth with an RF output frequency range of 100 MHz to
2.7 GHz. An optional LVDS output can be used to convert the quadrature modulator output to a clock
signal up to 800 MHz. Total power consumption is less than 350 mW with the LVDS output and 334 mW
with the analog RF output.
The AFE7070 package is a 7-mm × 7mm 48-pin QFN package. The AFE7070 is specified over the
full industrial temperature range (–40°C to 85°C).
