GN1155
Overview
The GN1155 is an integrated highly flexible bi-directional laser driver and limiting amplifier for SFP, SFF, and SFP+ applications.
The transmit path consists of optional equalization and a VCSEL laser driver that supports both cathode and differential drive. Anode drive is supported for certain configurations. The receive path is comprised of a limiting amplifier with programmable bandwidth. 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, and output mute.
Two different configuration profiles optimized for different data rates can be programmed into the GN1155. The active profile is selected through the RS0 pin.
Features/Highlights
- Multi-rate operation up to 11.3Gbps
- Fibre Channel multi-rate optimization via RS0 input
- Single 3.3V supply
Key Applications
- 850nm and 1310nm VCSEL-based SFP, SFF, and SFP+ transceivers
