AD9239:  Quad, 12-Bit, 170 MSPS/210 MSPS/250 MSPS Serial Output 1.8 V ADC

Product Details


The AD9239 is a quad, 12-bit, 250 MSPS analog-to-digital converter (ADC) with an on-chip temperature sensor and a high speed serial interface. It is designed to support digitizing high frequency, wide dynamic range signals with an input bandwidth up to 780 MHz. The output data are serialized and presented in packet format, consisting of channel-specific information, coded samples, and error correction code.

The ADC requires a single 1.8 V power supply and the input clock may be driven differentially with a sine wave, LVPECL, TTL, 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 145 mW per channel with the digital link still in operation when standby operation is enabled.

Fabricated on an advanced CMOS process, the AD9239 is avail-able in a Pb-free/RoHS-compliant, 72-lead LFCSP package. It is specified over the industrial temperature range of −40°C to +85°C.

Product Highlights

  1. Four ADCs are contained in a small, space-saving package.
  2. An on-chip PLL allows users to provide a single ADC sampling clock, and the PLL distributes and multiplies up to produce the corresponding data rate clock.
  3. Coded data rate supports up to 4.0 Gbps per channel. Coding includes scrambling to ensure proper dc common mode, embedded clock, and error correction.
  4. The AD9239 operates from a single 1.8 V power supply.
  5. Flexible synchronization schemes and programmable mode pins.
  6. On-chip temperature sensor.
