DESCRIPTION
TheLTM®9008-14/LTM9007-14/LTM9006-14are8-chan-
nel,simultaneoussampling14-bitA/Dconvertersdesigned
for digitizing high frequency, wide dynamic range signals.
AC performance includes 73dB SNR and 90dB spurious
free dynamic range (SFDR). Low power consumption per
channel reduces heat in high channel count applications.
Integrated bypass capacitance and flowthrough pinout
reduces overall board space requirements.

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).

Communications
+
–
The ENC and ENC inputs may be driven differentially
or single-ended with a sine wave, PECL, LVDS, TTL, or
CMOS inputs. An internal clock duty cycle stabilizer al-
lows high performance at full speed for a wide range of
clock duty cycles.
