Corebai Microelectronics CBM99D10BQ

The CBM99D10 is a direct digital synthesizer (DDS) with an integrated 14-bit DAC, supporting up to 1 GSPS sample rate and capable of generating 400 MHz sine waveforms. Users can control the DDS output signal via internal frequency, phase, and amplitude control words. The DDS supports rapid frequency hopping, achieving a tuning resolution of 0.23 Hz using a 32-bit accumulator at 1 GSPS sample rate. This DDS also features fast phase and amplitude switching. Users can program the internal control registers of the CBM99D10 via a serial I/O port to control the device. The CBM99D10 integrates static RAM to support multiple combinations of frequency, phase, and/or amplitude modulation. The CBM99D10 also supports a user-defined numerically controlled digital ramp operating mode, in which frequency, phase, or amplitude varies linearly over time. The CBM99D10's built-in high-speed parallel data input port enables direct frequency, phase, amplitude, or polar modulation to support more advanced modulation schemes.
