Broadcom Inc. 2 MBd Optical Transmitter for SERCOS Applications, 2x4, RoHS Compliant HFBR-1602Z

The HFBR-0600Z components are capable of operation at symbol rates from DC to over 2 MBd and distances from 0 to over 20 metres. The HFBR-1602Z and HFBR-1604Z transmitters contain a 655-nm AlGaAs emitter capable of efficiently launching optical power into 1000 mm plastic optical fiber. The optical output is specified at the end of 0.5 m of plastic optical fiber. The HFBR-1604Z is a selected version of the HFBR-1602Z, with power specified to meet the SERCOS high attenuation specifications. The HFBR-2602Z receiver incorporates an integrated photo IC containing a photodetector and dc amplifier driving an open-collector Schottky output transistor. The HFBR-2602Z is designed for direct interfacing to popular logic families. The absence of an internal pullup resistor allows the open-collector output to be used with logic families such as CMOS requiring voltage excursions higher than VCC. The HFBR-2602Z has a dynamic range of 15 dB.
