PRODUCT DESCRIPTION
The AD9289 is a quad 8-bit, 65 MSPS analog-to-digital conver-
ter (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 up to a 65 MSPS conversion rate and is
optimized for outstanding dynamic performance where a small
package size is critical.
The ADC requires a single, 3 V power supply and an 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 (DCO) for
capturing data on the output and a frame clock (FCO) trigger
for signaling a new output byte are provided. Power-down is
supported. The ADC typically consumes 7 mW when enabled.
Fabricated on an advanced CMOS process, the AD9289 is
available in a 64-ball mini-BGA package (64-BGA). 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.
A data clock out (DCO) is provided, which operates up to
260 MHz and supports double-data rate operation (DDR).
3.
The outputs of each ADC are serialized LVDS with data
rates up to 520 Mbps (8 bits × 65 MSPS).
4.
The AD9289 operates from a single 3.0 V power supply.
5.
The internal clock duty cycle stabilizer maintains
performance over a wide range of input clock duty cycles.
