Dual 14G CDR with integrated VCSEL driver and limiting amplifier
The GN2017 is an integrated highly-flexible bi-directional CDR, laser driver and limiting amplifier for 16G Fibre Channel, and FCoE SFP+ VCSEL based applications.
The GN2017 extends the reach and robustness of high-speed serial links by compensating for losses in the transmission medium and by resetting the jitter budget.
The transmit path consists of optional equalization, a multi-rate CDR and a VCSEL laser driver.
The receive path is comprised of a limiting amplifier, a multi-rate CDR, and programmable output pre-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 rise/fall times.
The GN2017 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 GN2017 is configurable for multi-rate operation. Two configuration profiles optimized for different data rates can be programmed into the GN2017.
The GN2017 also offers integrated laser safety features.
The GN2017 device is packaged in a small outline 5mm × 5mm, 32-pin, high-frequency QFN package with exposed pad.
The GN2017 is Pb-free and the encapsulation compound does not contain halogenated flame retardant.
