Data Sheet

AD9257S-CSL

Octal, 14-Bit, 65 MSPS Serial LVDS 1.8 V Analog-to-Digital Converter

FEATURES

GENERAL DESCRIPTION

► Low power: 55 mW per channel at 65 MSPS with scalable power

options

► SNR = 75.5 dB (to Nyquist)

The AD9257S-CSL is an octal, 14-bit, 65 MSPS analog-to-digital

converter (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 65 MSPS and is optimized

for outstanding dynamic performance and low power in applications

where a small package size is critical.

► SFDR = 91 dBc (to Nyquist)

► DNL = ±0.6 LSB (typical), INL = ±1.1 LSB (typical)

► Serial LVDS (ANSI-644, default)

► Low power, reduced signal option (similar to IEEE 1596.3)

► Data and frame clock outputs

► 650 MHz full power analog bandwidth

► 2 V p-p input voltage range

The ADC requires a single 1.8 V power supply and low voltage,

positive emitter-coupled logic (LVPECL)-/ CMOS-/low voltage dif-

ferential signaling (LVDS)-compatible sample rate clock for full

performance operation. No external reference or driver components

are required for many applications.

► 1.8 V supply operation

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 1 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).

► Serial port control

► Full chip and individual channel power-down modes

► Flexible bit orientation

► Built-in and custom digital test pattern generation

► Programmable clock and data alignment

► Programmable output resolution

► Standby mode

COMMERCIAL SPACE FEATURES

► Military temperature range (−55°C to +125°C)

► Wafer diffusion lot traceability

► Radiation lot acceptance test (RLAT)

► Total ionizing dose (TID)

► Radiation benchmark

► Single event latch-up (SEL)

The AD9257S-CSL is available in an RoHS-compliant, 64-lead lead

frame chip scale package (LFCSP). The device is specified over

the −55°C to +125°C temperature range. This product is protected

by a U.S. patent. Additional application and technical information

can be found in the Commercial Space Products Program brochure

and the AD9257 data sheet.

APPLICATIONS

PRODUCT HIGHLIGHTS

► Low Earth orbit (LEO) space payloads

► Quadrature and diversity radio receiver

► Optical imaging

1. Small Footprint. Eight ADCs are contained in a small, space-

saving package.

2. Low Power of 55 mW/Channel at 65 MSPS with Scalable

Power Options.

3. Ease of Use. A DCO is provided that operates at frequencies of

up to 455 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 with the AD9637 (12-Bit Octal ADC).
