FEATURES  
DESCRIPTION  
TheLTC®2268-14/LTC2267-14/LTC2266-14are2-channel,  
simultaneous sampling 14-bit A/D converters designed  
for digitizing high frequency, wide dynamic range signals.  
They are perfect for demanding communications applica-  
tions with AC performance that includes 73.4dB SNR and  
88dB spurious free dynamic range (SFDR). Ultralow jitter

The digital outputs are serial LVDS to minimize the num-  
ber of data lines. Each channel outputs two bits at a time  
(2-lane mode). At lower sampling rates there is a one bit  
per channel option (1-lane mode). The LVDS drivers have  
optional internal termination and adjustable output levels  
to ensure clean signal integrity.

The ENC and ENC inputs may be driven differentially  
or single-ended with a sine wave, PECL, LVDS, TTL, or
