Dual, 12-Bit, 80 MSPS/125 MSPS Serial LVDS 1.8 V Analog-to-Digital Converter
The ADC requires a single 1.8 V power supply and LVPECL-/ CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.
The ADC automatically multiplies the sample rate clock for the appropriate LVDS serial data rate. A data clock output (DCO) for capturing data on the output and a frame clock output (FCO) for signaling a new output byte are provided. Individual channel power-down is supported; the AD9635 typically consumes less than 2 mW in the full power-down state. The ADC provides several features designed to maximize flexibility and minimize system cost, such as programmable output clock and data alignment and digital test pattern generation. The available digital test patterns include built-in deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port interface (SPI).
The AD9635 is available in a RoHS-compliant, 32-lead LFCSP. It is specified over the industrial temperature range of −40°C to +85°C. This product is protected by a U.S. patent.
- Small Footprint. Two ADCs are contained in a small, spacesaving package.
- Low Power. The AD9635 uses 115 mW/channel at 125 MSPS with scalable power options.
- Pin Compatibility with the AD9645, a 14-Bit Dual ADC.
- Ease of Use. A data clock output (DCO) operates at frequencies of up to 500 MHz and supports double data rate (DDR) operation.
- User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.

Virtual Eval - BETA
Virtual Eval is a web application to assist designers in product evaluation of ADCs, DACs, and other ADI products. Using detailed models on Analog’s servers, Virtual Eval simulates crucial part performance characteristics within seconds. Configure operating conditions such as input tones and external jitter, as well as device features like gain or digital down-conversion. Performance characteristics include noise, distortion, and resolution, FFTs, timing diagrams, response plots, and more.
