SFP Controller for Dual Rx Interface
To achieve best results, it is recommended that the power
supply is decoupled with a 0.01FF or a 0.1FF capacitor.
Use high-quality, ceramic, surface-mount capacitors,
and mount the capacitors as close as possible to the
V
SDA is an open-collector output on the device that
requires a pullup resistor to realize high logic levels. A
master using either an open-collector output with a pul-
lup resistor or a push-pull output driver can be used for
SCL. Pullup resistor values should be chosen to ensure
that the rise and fall times listed in the I
Characteristics table are within specification.
