概览
The GN2012 is an integrated bi-directional CDR and limiting amplifier for XFP SONET, 10GBase-LR Ethernet and 8.5Gb/s Fibre Channel applications.
The transmit path consists of optional input equalization, a multi-rate Tx CDR, and a de-emphasis 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 the option for polarity invert, loopback, output mute, and programmable output equalization.
The GN2012 is a highly-programmable device, with features supporting DWDM applications. These include a programmable slice level adjust, programmable limiting amplifier peaking, and programmable sampling phase.
GN2012 配置有集成模数转换器，可通过串行接口，提供有关电源电压、芯片温度和眼图监视器的数字诊断信息。
The GN2012 is configurable for multi-rate operation, and can support both 8G Fibre Channel, 10GbE and SONET OC-192 in a single device.
The GN2012 device is packaged in a small outline 5mm × 5mm 32-pin, high-frequency QFN package, with exposed pad. The GN2012 is Pb-free, and the encapsulation compound does not contain halogenated flame retardant. This component and all homogeneous sub-components are RoHS compliant.
