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. The ADC requires a single 1.8 V power supply. The input clock can be driven differentially with a sine wave， LVPECL， CMOS， or LVDS. A clock duty cycle stabilizer allows high performance at full speed with a wide range of clock duty cycles. The on-chip reference eliminates the need for external decoupling and can be adjusted by means of SPI control. Various power-down and standby modes are supported. The ADC typically consumes 150 mW per channel with the digital link still in operation when standby operation is enabled.Fabricated on an advanced CMOS process， the AD9639 is available in a Pb-free/RoHS-compliant， 72-lead LFCSP package. It is specified over the industrial temperature range of −40°C to +85°C.
