AFBR-2555ARZ Optical 650nm receiver with reinforced metal housing for Sercos applications
Categories: Hardware Components
- Design ensures highest mechanical stability for the harsh industrial environment
- Enhanced mechanical stability during installation and usage in end applications
- Immune to electromagnetic disturbances from external devices
- Significantly improved signal integrity
The Broadcom AFBR-2555ARZ Receiver is housed in solid dual-in-line metal package. For reinforcement, an approx. 0.3 mm thick and 3 mm wide stainless steel brace was introduced. This design ensures highest mechanical stability for the harsh industrial environment.
The stainless steel brace has a surface treatment for easy wave soldering to the PCB, which significantly enhances the mechanical stability during installation and the usage in end applications.
Due to the integrated photodiode and a symmetrical layout, the receiver not only convinces with the mechanical stability. The new fully-symmetrical IC with an integrated photodiode is inherently immune to electromagnetic disturbances from external devices such as neighboring switchgears. With an average optical input power sensitivity of -23 dBm, the new receiver component shows significantly improved signal integrity compared with a legacy receiver component. Supported are Sercos applications with a data rate of 4, 8 and 16 MBd. We recommend using the receiver AFBR-2555ARZ together with the mechanically reinforced transmitter AFBR-1555ARZ.
