AD9643BCPZ-210

AD9643BCPZ-210 is a dual, 14bit analogue-to-digital converter (ADC) with sampling speeds of upto 210MSPS. It is designed to support communications applications where low cost, small size, wide bandwidth, and versatility are desired. The dual ADC cores feature a multistage, differential pipelined architecture with integrated output error correction logic. Each ADC features wide bandwidth inputs supporting a variety of user-selectable input ranges. An integrated voltage reference eases design considerations. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle, allowing the converter to maintain excellent performance. It is used in applications such as communications, diversity radio systems, multimode digital receivers (3G), TD-SCDMA, WiMax, WCDMA, CDMA2000, GSM, EDGE, LTE, I/Q demodulation systems, smart antenna systems, general-purpose software radios, ultrasound equipment, broadband data applications.

• Offset error is ±10mV maximum, differential nonlinearity is ±0.75LSB maximum
• Temperature drift offset error is ±5ppm/°C typical at (AVDD = 1.8V, DRVDD = 1.8V)
• Signal to noise ratio is 72.6dBFS typical at (fIN = 30MHz, AVDD = 1.8V, DRVDD = 1.8V)
• Spurious free dynamic range is 90dBc typical at (fIN = 30MHz, AVDD = 1.8V, DRVDD = 1.8V)
