GN2012
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.

在 2018 年进行了大量演示和 alpha 模块测试之后，双密度版本的四通道小型可插拔 (QFSP) 多源协议 (MSA) 模块标准有望成为新线卡的规则。QSFP-DD 热潮的隐含意义不是模块本身的物理特性，而是转向先进信令方法的趋势。十年前，QSFP28 的问世预示着使用 NRZ 信令的 25Gbps 电通道即将占据主导地位。如今，QSFP-DD 及其更庞大的表亲 —— 八进制 SFP 或 OSFP ，都使用 PAM4 信令。其用得最多的是 50Gbps 通道。但 QSFP-DD 足够灵活，可以在各种实施中使用八通道接口：25G x 8 用于 200Gbit 以太网，50G x 8 用于 400Gbit 以太网，可能还有一些早期的 100G x 8 用于预标准 800Gbit 以太网。
