LTC2152-12/
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 ENCinputs 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.
