Fiber Optic Data

Analog Devices provides discrete rate, multirate, and continuous tuning clock and data recovery ICs for equipment designs, including metro, long haul, DWDM, and FSO applications. ADI CDRs allow easy integration into protocol agnostic applications, automatically locking onto incoming data streams at any rate between 12.3 Mbps to 2.7 Gbps without the aid of a reference clock while reporting the acquired data rate over the I2C interface.

The interface to the optical cable requires specific physical layer transmitters and receivers to manage signal conversion between the electrical and optical domains. This conversion is normally performed in an optical transceiver module. We provide a family of products that drives optical transmitter devices such as lasers or silicon photonics along with receivers that amplify, reshape, and retime signals from a photodiode. These products are currently offered for bitrates up to 50 Gbps. We also offer control and power management products that are optimized for optical module applications to complete the chipset needed in an optical module.

Analog Devices laser diode driver ICs work with Fabry-Perot, DFB, and VCSELs, and the ICs support continuous mode data rates from 50 Mbps to 11.3 Gbps. Featuring dual-loop control of extinction ratio and average power, our laser diode drivers maintain a preset OMA or optical average power output by sensing and processing the laser MPD feedback with on-chip or off-chip solutions. Our drivers support a variety of MSA-compatible modules such as SFP+, SFP with SFF-8472 Digital Diagnostics, SFF, 4× Fibre Channel, XFP, XENPAK, X2, and MSA-300.

Analog Devices’ optical modulator driver portfolio features operation over 32 Gbps, low dc power dissipation, integrated peak-detect functionality, and lower additive rms jitter. Our products support communication infrastructure (400 G 16 QAM, 100 G DP-QPSK), broadband gain stage and pre-amplifiers, broadband test and measurement equipment, and other applications.

Analog Devices high gain optical limiting amplifiers feature low power, low jitter, and excellent sensitivity performance. Our limiting amplifiers include receiver functions such as quantization, loss of signal detection, and SFF-8472-compliant average power measurement. Along with SFP, SFF, and GBIC MSA module designs, our amplifiers also support physical layer protocols that include 1 ×, 2 ×, and 4 × Fibre Channel, 10GBASE-LX4, multiple rate SONET/SDH up to OC-48 with FEC, and Gigabit Ethernet.

Analog Devices optical transimpedance amplifiers offer a complete, high performance, single chip solution for converting photodiode current into a differential voltage input. Supporting data rates from 155 Mbps to 11.1 Gbps, our transimpedance amplifiers are ideally suited for data communications and telecommunications applications supporting lay protocols including 1×, 2×, 4×, and 8× Fibre Channel, 10GBASE-LX4, SONET/SDH up to OC-192 with FEC, and 10 Gigabit Ethernet. Our transimpedance amplifiers feature low input referred noise current, high input current, and low power dissipation.
