SFP+ Controller with Digital LDD Interface

Applications Information

Power-Supply Decoupling

To achieve best results, it is recommended that the power

supply is decoupled with a 0.01µF or a 0.1µF capacitor.

Use high-quality, ceramic, surface-mount capacitors,

and mount the capacitors as close as possible to the

VCC and GND pins to minimize lead inductance.

SDA and SCL Pullup Resistors

SDA is an open-collector output on the DS1874 that

requires a pullup resistor to realize high logic levels. A

master using either an open-collector output with a

pullup resistor or a push-pull output driver can be uti-

lized for SCL. Pullup resistor values should be chosen

to ensure that the rise and fall times listed in the I2C AC

Electrical Characteristics table are within specification.
