GENERAL DESCRIPTION
The AD9639 is a quad, 12-bit, 210 MSPS analog-to-digital converter (ADC) with an on-chip temperature sensor and a high speed serial interface. It is designed to support the digitizing of high frequency, wide dynamic range signals with an input bandwidth of up to 780 MHz. The output data is serialized and presented in packet format, consisting of channel-specific information, coded samples, and error code correction.
