excellent noise performance. Maximum DC specs include  
±±.5LSB ꢀIL, ±1LSB DIL (no missing codes).  
The digital output can be either differential LVDS or  
single-ended CMOS. There are two format options for the  
CMOS outputs: a single bus running at the full data rate or  
demultiplexed buses running at half data rate. A separate  
output power supply allows the CMOS output swing to  
range from 0.5V to ±.6V.  
APPLICATIONS  
n
Telecommunications  
+
The EIC and EIC inputs may be driven differentially  
or single-ended with a sine wave, PECL, LVDS, TTL or  
CMOS inputs. An optional clock duty cycle stabilizer al-  
lows high performance at full speed with a wide range of  
clock duty cycles.
