GENERAL DESCRIPTION
The AD9410 is a 10-bit monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and is opti-
mized for high-speed conversion and ease of use. The product
operates at a 210 MSPS conversion rate, with outstanding
dynamic performance over its full operating range.
The ADC requires a 5.0 V and 3.3 V power supply and up to a
210 MHz differential clock input for full performance operation.
No external reference or driver components are required for many
applications. The digital outputs are TTL/CMOS-compatible,
and separate output power supply pins also support interfacing
with 3.3 V logic.
The clock input is differential and TTL/CMOS-compatible. The
10-bit digital outputs can be operated from 3.3 V (2.5 V to 3.6 V)
supplies. Two output buses support demultiplexed data up to
105 MSPS rates, and binary or two’s complement output coding
format is available. A data sync function is provided for timing-
dependent applications. An output clock simplifies interfacing to
external logic. The output data bus timing is selectable for parallel
or interleaved mode, allowing for flexibility in latching output data.
Fabricated on an advanced BiCMOS process, the AD9410
is available in an 80-lead surface-mount plastic package
(PowerQuad^®2) specified over the industrial temperature range
(–40°C to +85°C).
PRODUCT HIGHLIGHTS
High Resolution at High Speed—The architecture is specifically
designed to support conversion up to 210 MSPS with outstand-
ing dynamic performance.
Demultiplexed Output—Output data is decimated by two and
provided on two data ports for ease of data transport.
Output Data Clock—The AD9410 provides an output data
clock synchronous with the output data, simplifying the timing
between data and other logic.
Data Synchronization—A DS input is provided to allow for
synchronization of two or more AD9410s in a system, or
to synchronize data to a specific output port in a single
AD9410 system.
