GENERAL DESCRIPTION
The AD9222 is an octal, 12-bit, 40/50/65 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.

Figure 1.
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 AD9222 is available in an RoHS compliant, 64-lead LFCSP. It is
specified over the industrial temperature range of 40°C to +85°C.
PRODUCT HIGHLIGHTS
1. Small Footprint. Eight ADCs are contained in a small,
space-saving package.
2. Low power of 114 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 AD9212 (10-bit)
and AD9252 (14-bit).
