GENERAL DESCRIPTION
The AD9252 is an octal, 14-bit, 50 MSPS ADC with an on-chip
sample-and-hold circuit designed for low cost, low power, small size,
and ease of use. Operating at a conversion rate of up to 50 MSPS,
it 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 (DCO)
for capturing data on the output and a frame clock (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 AD9252 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 package.
2.
