SFP+ Controller with Analog LDD Interface

ABSOLUTE MAXIMUM RATINGS

Voltage Range on MON1–MON4, RSEL,

IN1, LOS, TXF, and TXD Pins

Relative to Ground .................................-0.5V to (VCC + 0.5V)*

Voltage Range on VCC, SDA, SCL, OUT1,

RSELOUT, and LOSOUT Pins

Relative to Ground..............................................-0.5V to +4.2V

Operating Temperature Range ...........................-40°C to +95°C

Programming Temperature Range .........................0°C to +95°C

Storage Temperature Range .............................-55°C to +125°C

Soldering Temperature...........................Refer to the IPC/JEDEC

J-STD-020 Specification.

*Subject to not exceeding +4.2V.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

RECOMMENDED OPERATING CONDITIONS

(TA = -40°C to +95°C, unless otherwise noted.)
