Semtech GN1412

11.3G EML driver with integrated limiting amplifier

Add to Watch List

The GN1412 is an integrated bi-directional EML laser driver and limiting amplifier for SFP+ 10GBase-ER/ZR Ethernet and 8.5Gb/s Fibre Channel applications.  It is a highly-integrated, low-power, small-footprint device, that is ideal for small form factor optical modules.

The transmit path consists of optional input equalization and an EML laser driver. The receive path is comprised of a limiting amplifier with programmable equalization and output driver with programmable swing.  The transmit direction offers a highly-configurable eye shaping feature, including independently programmable rise and fall pre-emphasis, which allows for an optimal electrical and optical output. Both directions offer the option for polarity-invert, loopback, and output mute.

The GN1412 has an integrated analog to digital converter, which through the serial interface, provides digital diagnostic information on supply voltage, die temperature, and transmit optical power.

The GN1412 device is packaged in a small-outline 5mm × 5mm 32-pin, high-frequency QFN package with exposed pad. The GN1412 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant.
