1 GSPS orthogonal digital upconverter with built-in 18 bit IQ data path and 14 bit DAC
CBM99D57BQ.pdf | 1.26M

The CBM99D57 functions as a universal I/Q modulator and agile upconverter for communications systems. The CBM99D57 integrates a high speed, direct digital synthesizer (DDS), a high performance, high speed, 14-bit digital-to-analog converter (DAC), clock multiplier circuitry, digital filters, and other DSP functions onto a single chip. It provides baseband up conversion for data transmission in a wired or wireless communications system. It also provides excellent performance in terms of speed, power consumption and spectrum performance. The chip supports a 16-bit serial input mode for I/Q baseband data. The device can alternatively be programmed to operate either as a single tone, sinusoidal source or as an interpolating DAC. The chip achieves high speed internal sampling clock through a crystal oscillator, a high speed, divide-by-two input, and a low noise PLL.
