• Manufacturer Part Number: SY84782UMGTR
• Description: Low Power 2.5V 1.25Gbps FP/DFB Laser Diode Driver
• Manufacturer: MICREL [Micrel Semiconductor]

between the first bit and the last bit of a long string of
identical bits in a low data rate application. This leads to
higher pattern-dependent jitter in the transmitter signal.
0.1µF is found to be good for all applications from
155Mbps to 1.25Gbps.
AC-coupling the laser to the driver brings a solution to
the driver headroom problem at the expense of extra
components, loss of part of the modulation current
wasted in the pull-up network, and additional power
consumption.
