10-Bit, 135Msps ADC
The LTC
2234 is a 135Msps, sampling 10-bit A/D con-
verter designed for digitizing high frequency, wide dy-
namic range signals. The LTC2234 is perfect for demand-
ing communications applications with AC performance
that includes 60.5dB SNR and 75dB spurious free dy-
namic range for signals up to 400MHz. Ultralow jitter of
0.15psRMS allows undersampling of IF frequencies with
excellent noise performance.
DC specs include
±0.2LSB INL (typ), ±0.1LSB DNL (typ)
and
±0.8LSB INL, ±0.6LSB DNL over temperature. The
transition noise is a low 0.12LSBRMS.
A separate output power supply allows the CMOS output
swing to range from 0.5V to 3.6V.
The ENC+ and ENCinputs 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.
