LVDS Differential Outputs
(XO). The LMxxx - Series are designed for
applications requiring tight frequency stability,
wide temperature range, and low jitter. Operating
at 2.5 or 3.3 Vdc supply voltage, the LMxxx -
Series provides LVDS Differential Outputs with an
enable / disable function. The design utilizes PLL
multiplication to produce a high frequency output
from a low frequency fundamental crystal.
Frequency Stabilities Available:
+/-20 ppm, +/-25 ppm, +/-50 ppm or +/-100 ppm
Temperature Ranges Available:
0 to 70°C, -40 to 85°C, 0 to 85°C or -20 to 70°C
Low Jitter <1ps RMS
