... PLL / Clock Generation integrated DAC in the BCM3033 is a 10-bit, 114-MS/s DAC with differential analog outputs. Operation of the BCM3033 involves a serial or parallel bit stream input that can be passed through the FEC encoder or directly to the modulator. The resulting data is interpolated, filtered, and modulated to the IF carrier. The modulator provides ...
