LTC2151-12/LTC2150-12

Single 12-Bit 250Msps/

210Msps/170Msps ADCs

DESCRIPTION

The LTC®2152-12/LTC2151-12/LTC2150-12 are a family

of 250Msps/210Msps/170Msps 12-bit A/D converters

designed for digitizing high frequency, wide dynamic range

signals. They are perfect for demanding communications

applications with AC performance that includes 68.5dB

SNR and 90dB spurious free dynamic range (SFDR). The

1.25GHz input bandwidth allows the ADC to undersample

high input frequencies with good performance. The latency

is only six clock cycles.

DC specs include ±0.26LSB INL (typ), ±0.16LSB DNL (typ)

and no missing codes over temperature. The transition

noise is 0.54LSBRMS.

The digital outputs are double-data rate (DDR) LVDS.

The ENC+ and ENC– inputs can be driven differentially 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.
