135Msps: LTC2221 (12-Bit), LTC2231 (10-Bit)

64-Pin 9mm x 9mm QFN Package

The LTC

2230 and LTC2231 are 170Msps/135Msps, sam-

pling 10-bit A/D converters designed for digitizing high

frequency, wide dynamic range signals. The LTC2230/

LTC2231 are perfect for demanding communications

applications with AC performance that includes 61dB SNR

and 75dB spurious free dynamic range for signals

up to 200MHz. Ultralow jitter of 0.15ps

RMS

allows

undersampling of IF frequencies with excellent noise

performance.

DC specs include

±0.2LSB

INL (typ),

±0.1LSB

DNL (typ)

and no missing codes over temperature. The transition

noise is a low 0.12LSB

RMS

The digital outputs can be either differential LVDS, or

single-ended CMOS. There are three format options for

the CMOS outputs: a single bus running at the full data rate

or two demultiplexed buses running at half data rate with

either interleaved or simultaneous update. A separate

output power supply allows the CMOS output swing to

range from 0.5V to 3.6V.

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 allows high

performance at full speed for a wide range of clock duty

cycles.
