GENERAL DESCRIPTION
The ML0XX18 is an external modulator driver for 10Gb/s optical communication systems. Output voltage swing, output
voltage offset, and output voltage cross-point are adjustable by controls of current inputs. A D-FF and a selector are
integrated on the chip to implement selectable re-timing/bypass function. Data and clock inputs have high sensitivity of
200mV differential amplitude. Both DC/AC-coupled connections are allowed for the data inputs. Clock input supports
AC-coupled connection. The ML0XX18 is available in a 32-pin Small Lead-frame Package (SLP-type) or in a die form.

Mitsubishi Electric Corporation puts the maximum effort into
making semiconductor products better and more reliable,
but there is always the possibility that trouble may occur
with them. Trouble with semiconductors may lead to personal
injury, fire or property damage. Remember to give due
consideration to safety when making your circuit designs,
with appropriate measures such as (
ⅰ
)placement of
Substitutive, auxiliary circuits, (
ⅱ
)use of non-flammable
material or (
ⅲ
)prevention against any malfunction or mishap.
