Example: Part Number
L143-155.52M = LVDS Output,
0 to 70, +/-20ppm, 3.3Vdc, E/D Pad 1, Output Frequency 155.52MHz
To order an L143 with an output frequency of:
25 MHz = L143-025.0M
44.736 MHz = L143-044.736M
155.52 MHz = L143-155.52M
Attention: Models L242, L243, L244 and L235 are not available above 260 MHz.
