DAC1203D160
Dual 12 bits DAC, up to 160 MHz, 2 x interpolating
Rev. 03 — 2 July 2012
Product data sheet
1. General description
The DAC1203D160 is optimized to reduce architecture complexity and overall system
cost. The Digital-to-Analog Converter (DAC) leads dynamic performance in multi-carrier
support, because of its direct IF conversion capabilities. With an internal sampling rate up
to 160 MHz, the DAC1203D160 is an extremely competitive solution for broadband
wireless systems transmitters, as well as a wide range of other applications.
2. Features
