LTC2159

16-Bit, 20Msps

Low Power ADC

FeaTures

DescripTion

TheLTC^®2159isasampling16-bitA/Dconverterdesigned

for digitizing high frequency, wide dynamic range signals.

It is perfect for demanding communications applications

with AC performance that includes 77dB SNR and 90dB

spurious free dynamic range (SFDR). Ultralow jitter of

77dB SNR

90dB SFDR

Low Power: 43mW

Single 1.8V Supply

CMOS, DDR CMOS, or DDR LVDS Outputs

Selectable Input Ranges: 1V to 2V

0.07ps

allows undersampling of IF frequencies with

P-P

RMS

550MHz Full Power Bandwidth S/H

Optional Data Output Randomizer

Optional Clock Duty Cycle Stabilizer

Shutdown and Nap Modes

excellent noise performance.

DC specs include 2LSB INL (typ), 0.5LSB DNL (typ)

and no missing codes over temperature. The transition

noise is 3.2LSB

RMS

Serial SPI Port for Configuration

The digital outputs can be either full rate CMOS, double

data rate CMOS, or double data rate LVDS. A separate

output power supply allows the CMOS output swing to

range from 1.2V to 1.8V.

Communications

The ENC and ENC inputs may be driven differentially

or single-ended with a sine wave, PECL, LVDS, TTL, or

CMOS inputs. An optional clock duty cycle stabilizer al-

lows high performance at full speed for a wide range of

clock duty cycles.
