Product Description

Product Details
The AD9652 is a dual, 16-bit analog-to-digital converter (ADC) with sampling speeds of up to 310 MSPS. It is designed to support demanding, high speed signal processing applications that require exceptional dynamic range over a wide input frequency range (up to 465 MHz). Its exceptional low noise floor of −157.6 dBFS and large signal spurious-free dynamic range (SFDR) performance (exceeding 85 dBFS, typical) allows low level signals to be resolved in the presence of large signals.
The dual ADC cores feature a multistage, pipelined architecture with integrated output error correction logic. A high performance on-chip buffer and internal voltage reference simplify the inter-face to external driving circuitry while preserving the exceptional performance of the ADC.
The AD9652 can support input clock frequencies of up to 1.24 GHz with a 1, 2, 4, and 8 integer clock divider used to generate the ADC sample clock. A duty cycle stabilizer is provided to compensate for variations in the ADC clock duty cycle. The 16-bit output data (with an overrange bit) from each ADC is interleaved onto a single LVDS output port along with a double data rate (DDR) clock. Programming for setup and control are accomplished using a 3-wire SPI-compatible serial interface.
The AD9652 is available in a 144-ball CSP_BGA and is specified over the industrial temperature range of −40°C to +85°C. This product is protected by pending U.S. patents.
**PRODUCT HIGHLIGHTS**
1. Integrated dual, 16-bit, 310 MSPS ADCs.
2. On-chip buffer simplifies ADC driver interface.
3. Operation from a 3.3 V and 1.8 V supply and a separate digital
output driver supply accommodating LVDS outputs.
4. Proprietary differential input maintains excellent SNR
performance for input frequencies of up to 485 MHz.
5. SYNC input allows synchronization of multiple devices.
6. Three-wire, 3.3 V or 1.8 V SPI port for register programming
and readback.
