GENERAL DESCRIPTION
The AD9287 is a quad, 8-bit, 100 MSPS analog-to-digital con-
verter (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 100 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 AD9287 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 133 mW/channel at 100 MSPS.
3.
Ease of Use. A data clock output (DCO) is provided that
operates at frequencies of up to 400 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 AD9219 (10-bit),
AD9228 (12-bit), and AD9259 (14-bit).
