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®).

GENERAL DESCRIPTION  
The AD9228 is available in a Pb-free, 48-lead LFCSP package. It is  
specified over the industrial temperature range of −40°C to +85°C.  
The AD9228 is a quad, 12-bit, 40/65 MSPS analog-to-digital  
converter (ADC) with an on-chip sample-and-hold circuit that  
is 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.  
PRODUCT HIGHLIGHTS  
1. Small Footprint. Four ADCs are contained in a small, space-  
saving package; low power of 119 mW/channel at 65 MSPS.  
2. Ease of Use. A data clock output (DCO) is provided that  
operates up to 390 MHz and supports double data rate  
operation (DDR).  
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.  
3. User Flexibility. Serial port interface (SPI) control offers a wide  
range of flexible features to meet specific system requirements.  
The ADC automatically multiplies the sample rate clock for the  
appropriate LVDS serial data rate. A data clock (DCO) for  
4. Pin-Compatible Family. This includes the AD9287 (8-bit),  
AD9219 (10-bit), and AD9259 (14-bit).
