AD9219:  Quad, 10-Bit, 40/65 MSPS Serial LVDS 1.8 V A/D Converter

Product Description

The AD9219 is a quad, 10-bit, 40/65 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 65 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

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 and typically consumes less than 2 mW when all channels are disabled.

The ADC contains several features designed to maximize flexibility and minimize system cost, such as programmable clock and data alignment and programmable 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 AD9219 is available in an RoHS compliant, 48-lead LFCSP. It is specified over the industrial temperature range of −40°C to +85°C.

Product Highlights

  1. Small Footprint. Four ADCs are contained in a small, space-saving package.
  2. Low power of 94 mW/channel at 65 MSPS.
  3. Ease of Use. A data clock output (DCO) is provided that operates at frequencies of up to 390 MHz and supports double data rate (DDR) operation.
  4. User Flexibility. The SPI control offers a wide range of flexible features to meet specific system requirements.
  5. Pin-Compatible Family. This includes the AD9287 (8-bit), AD9228 (12-bit), and AD9259 (14-bit).
