GN2010D

Overview

The GN2010D is an integrated bi-directional CDR, DFB/FP laser driver and limiting amplifier for XFP & SFP+ SONET, 10GBase-LR 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, a multi-rate Tx CDR, and a DFB laser driver. The receive path is comprised of a limiting amplifier with programmable equalization, a multi-rate Rx CDR, and output de-emphasis. Both transmit and receive directions offer highly configurable eye shaping features, which allow for optimal electrical and optical outputs. Both directions also offer the option for polarity-invert, loopback, output mute, and programmable output equalization.

The GN2010D has an integrated analog to digital converter, which through the serial interface, provides digital diagnostic information on supply voltage, die temperature, laser bias current, and transmit optical power. The GN2010D is configurable for multi-rate operation. The GN2010D also offers integrated laser safety features.

The GN2010D device is packaged in a small-outline 5mm × 5mm 32-pin, high-frequency QFN package with exposed pad. The GN2010D is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous sub-components are RoHS compliant.
