11-Bit, 105Msps ADC
The LTC
2222-11 is a 105Msps, sampling 11-bit A/D
converter designed for digitizing high frequency, wide
dynamic range signals. The LTC2222-11 is perfect for
demanding communications applications with AC perfor-
mance that includes 65.4dB SNR and 80dB spurious free
dynamic range for signals up to 150MHz. Ultralow jitter of
0.15psRMS allows undersampling of IF frequencies with
excellent noise performance.
DC specs include
±0.15LSB INL (typ), ±0.1LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 0.25LSBRMS.
A separate output power supply allows the CMOS output
swing to range from 0.5V to 3.3V.
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.
