The ISLA214P50IRZ is a 14-bit Analog-to-digital Converter (ADC) designed with Intersils proprietary FemtoCharge™ technology on a standard CMOS process. The device utilizes two time-interleaved 250MSPS unit ADC to achieve the ultimate sample rate of 500MSPS. A single 500MHz conversion clock is presented to the converter and all interleave clocking is managed internally. The proprietary Intersil Interleave Engine performs automatic correction of offset, gain and sample time mismatches between the units ADC to optimize performance. A serial peripheral interface port allows for extensive configurability of the A/D. The SPI also controls the interleave correction circuitry, allowing the system to issue offline and continuous calibration commands as well as configure many dynamic parameters.

• Automatic fine interleave correction calibration
• Clock duty cycle stabilizer
• Programmable built-in test patterns
• SPI programmable fine gain and offset control
• Support for multiple ADC synchronization
• Optimized output timing
• Nap and sleep modes
• Data output clock
• DDR LVDS-compatible or LVCMOS outputs
• Selectable clock divider

The AD9122BCPZ is a dual 16-bit high dynamic range Digital-to-analog Converter (DAC) provides a sample rate of 1230MSPS, permitting multicarrier generation up to the Nyquist frequency. It includes features optimized for direct conversion transmits applications. The DAC outputs are optimized to interface seamlessly with analog quadrature modulators, such as the ADL537x F-MOD series from Analog Devices Inc. A 4-wire serial port interface provides for programming/read-back of many internal parameters. Full-scale output current can be programmed over a range of 8.7 to 31.7mA.

• Flexible LVDS interface allows word, byte or nibble load
• Gain, DC offset and phase adjustment for sideband suppression
• Multiple chip synchronization interfaces
• High performance, low noise PLL clock multiplier
• Digital inverse sinc filter

The LTC2309HF#PBF is a 8-channel 12-bit SAR Analog-to-digital Converter (ADC) with I²C compatible serial interface. This ADC includes an internal reference and a fully differential sample-and-hold circuit to reduce common mode noise. The ADC operates from an internal clock to achieve a fast 1.3µs conversion time. It operates from a single 5V supply and draws just 300µA at a throughput rate of 1ksps. The ADC enters nap mode when not converting, reducing the power dissipation. The low power consumption and small size make the ADC ideal for battery-operated and portable applications, while the 2-wire I²Ccompatibleserialinterfacemakes this ADC a good match for space-constrained systems.

• Guaranteed no missing codes
• Internal reference
• Internal 8-channel multiplexer
• Internal conversion clock
