GENERAL DESCRIPTION
The AD9265 is a 16-bit, 125 MSPS analog-to-digital converter
(ADC). The AD9265 is designed to support communications
applications where high performance combined with low cost,
small size, and versatility is desired.
The ADC core features a multistage, differential pipelined
architecture with integrated output error correction logic to
provide 16-bit accuracy at 125 MSPS data rates and guarantees
no missing codes over the full operating temperature range.
The ADC features a wide bandwidth differential sample-and-
hold analog input amplifier supporting a variety of user-selectable
input ranges. It is suitable for multiplexed systems that switch
full-scale voltage levels in successive channels and for sampling
single-channel inputs at frequencies well beyond the Nyquist rate.
Combined with power and cost savings over previously available
ADCs, the AD9265 is suitable for applications in communications,
instrumentation and medical imaging.

A differential clock input controls all internal conversion cycles. A
duty cycle stabilizer provides the means to compensate for vari-
ations in the ADC clock duty cycle, allowing the converters to
maintain excellent performance over a wide range of input clock
duty cycles. An integrated voltage reference eases design consid-
erations.
The ADC output data format is either parallel 1.8 V CMOS or
LVDS (DDR). A data output clock is provided to ensure proper
latch timing with receiving logic.
Programming for setup and control is accomplished using a 3-wire
SPI-compatible serial interface. Flexible power-down options
allow significant power savings, when desired. An optional on-
chip dither function is available to improve SFDR performance
with low power analog input signals.
The AD9265 is available in a Pb-free, 48-lead LFCSP and is speci-
fied over the industrial temperature range of −40°C to +85°C.
