LTC2220-1  
12-Bit,185Msps ADC  
U
FEATURES  
DESCRIPTIO  
The LTC®2220-1 is a 185Msps, sampling 12-bit A/D  
converter designed for digitizing high frequency, wide  
dynamic range signals. The LTC2220-1 is perfect for  
demanding communications applications with AC perfor-  
mance that includes 67.5dB SNR and 80dB spurious free  
dynamic range for signals up to 170MHz. Ultralow jitter of  
0.15psRMS allows undersampling of IF frequencies with  
excellent noise performance.  
Sample Rate: 185Msps  
67.5dB SNR up to 140MHz Input  
80dB SFDR up to 170MHz Input  
775MHz Full Power Bandwidth S/H  
Single 3.3V Supply  
Low Power Dissipation: 910mW  
LVDS, CMOS, or Demultiplexed CMOS Outputs  
Selectable Input Ranges: ±0.5V or ±1V  
No Missing Codes  
DC specs include ±0.7LSB INL (typ), ±0.5LSB DNL (typ)  
Optional Clock Duty Cycle Stabilizer  
and no missing codes over temperature. The transition  
Shutdown and Nap Modes  
noise is a low 0.5LSBRMS  
.
Data Ready Output Clock  
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 3.6V.  
The ENC+ and ENCinputs may be driven differentially or  
singleendedwithasinewave, PECL, LVDS, TTL, orCMOS  
inputs. An optional clock duty cycle stabilizer allows high  
performance at full speed for a wide range of clock duty  
cycles.  
Pin Compatible Family  
185Msps: LTC2220-1 (12-Bit)  
170Msps: LTC2220 (12-Bit), LTC2230 (10-Bit)
