LTC2152-14/
LTC2151-14/LTC2150-14
14-Bit 250Msps/
210Msps/170Msps ADCs
DESCRIPTION
The LTC®2152-14/LTC2151-14/LTC2150-14 are 250Msps/
210Msps/170Msps 14-bit A/D converters designed for
digitizing high frequency, wide dynamic range signals.
They are perfect for demanding communications applica-
tions with AC performance that includes 70dB SNR and
90dB spurious free dynamic range (SFDR). The 1.25GHz
input bandwidth allows the ADC to undersample high
frequencies with good performance. The latency is only
six clock cycles.
DC specs include ±0.85LSB INL (typ), ±0.25LSB DNL (typ)
and no missing codes over temperature. The transition
noise is 1.82LSBRMS.
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.
