The ADN2526 laser diode driver is designed for direct modulation of packaged laser diodes that have a differential resistance ranging from 5 Ω to 50 Ω. The active back-termination in the ADN2526 absorbs signal reflections from the TOSA end of the output transmission lines, enabling excellent optical eye quality to be achieved even when the TOSA end of the output transmission lines is significantly misterminated. ADN2526 is an SFP+ MSA-compliant device, and its small package and enhanced ESD protection provide the optimum solution for compact modules where laser diodes are packaged in low pin-count optical subassemblies.The modulation and bias currents are programmable via the MSET and BSET control pins. By driving these pins with control voltages, the user has the flexibility to implement various average optical power and extinction ratio control schemes, including closed-loop or look-up table control. The automatic laser shutdown (ALS) feature allows the user to turn on/off the bias and modulation currents by driving the ALS pin with a LVTTL logic source.The product is available in a space-saving 3 mm × 3 mm LFCSP specified from −40°C to +85°C.ApplicationsSONET OC-192 and SDH STM-64 optical transceivers10 Gb Fibre Channel transceivers10 Gb Ethernet optical transceiversSFP+/XFP/X2/XENPAK/XPAK/MSA 300 optical modules

The ADN2804 provides the receiver functions of quantization, signal level detect, clock and data recovery, and data retiming for 622 Mbps NRZ data. The ADN2804 automatically locks to 622 Mbps data without the need for an external reference clock or programming. In the absence of input data, the output clock drifts no more than ±5%. All SONET jitter requirements are met, including jitter transfer, jitter generation, and jitter tolerance. All specifications are quoted for −40°C to +85°C ambient temperature, unless otherwise noted.This device, together with a PIN diode and a TIA preamplifier, can implement a highly integrated, low cost, low power fiber optic receiver.The receiver’s front-end loss-of-signal (LOS) detector circuit indicates when the input signal level falls below a user-adjustable threshold. The LOS detect circuit has hysteresis to prevent chatter at the output.The ADN2804 is available in a compact 5 mm × 5 mm, 32-lead LFCSP.ApplicationsBPON ONTSONET OC-12WDM transpondersRegenerators/repeatersTest equipmentBroadband cross-connects and routers
