LTC2242-12  
12-Bit, 250Msps ADC  
U
FEATURES  
DESCRIPTIO  
The LTC®2242-12 is a 250Msps, sampling 12-bit A/D  
converter designed for digitizing high frequency, wide  
dynamic range signals. The LTC2242-12 is perfect for  
demanding communications applications with AC perfor-  
mancethatincludes65.4dBSNRand78dBSFDR.Ultralow  
jitter of 95fsRMS allows IF undersampling with excellent  
noise performance.  
Sample Rate: 250Msps  
65.4dB SNR  
78dB SFDR  
1.2GHz Full Power Bandwidth S/H  
Single 2.5V Supply  
Low Power Dissipation: 740mW  
LVDS, CMOS, or Demultiplexed CMOS Outputs  
Selectable Input Ranges: ±0.5V or ±1V  
DC specs include ±1.0LSB INL (typ), ±0.4LSB DNL (typ)  
and no missing codes over temperature.  
No Missing Codes  
Optional Clock Duty Cycle Stabilizer  
The digital outputs can be either differential LVDS, or  
single-ended CMOS. There are three format options for  
theCMOSoutputs:asinglebusrunningatthefulldatarate  
or two demultiplexed buses running at half data rate with  
either interleaved or simultaneous update. A separate  
output power supply allows the CMOS output swing to  
range from 0.5V to 2.625V.  
The ENC+ and ENCinputs may be driven differentially or  
singleendedwithasinewave, PECL, LVDS, TTL, orCMOS  
inputs. An optional clock duty cycle stabilizer allows high  
performance over a wide range of clock duty cycles.
