HFBR-0508Z Series HFBR-1528Z Transmitter HFBR-2528Z Receiver 10 Megabaud Versatile Link Fiber Optic Transmitter and Receiver for 1 mm POF and 200 m HCS(R) Data Sheet Description Features The HFBR-0508Z Series consists of a fiber-optic transmitter and receiver operating at a 650 nm wavelength (red). The HFBR-1528Z transmitter is an LED in a low cost plastic housing designed to efficiently couple power into 200 m diameter Hard Clad Silica (HCS) and 1 mm diameter Plastic optical fiber (POF). The HFBR-2528Z receiver incorporates a PIN detector and digital output IC compatible with CMOS and TTL logic families. RoHS-compliant Data transmission at signal rates of dc to 10 MBd Up to 50 meters distances with 1 mm Plastic Optical Fiber (POF) Up to 500 meters distances with 200 m Hard Clad Silica (HCS) Wide dynamic range receiver allows operation from zero to maximum link distance with a single transmitter drive current Link distances specified for variations in temperature, power supply, and fiber attenuation DC coupled receiver with CMOS/TTL output for easy designs: No data encoding or digitizing circuitry required Pulse width distortion (PWD) controlled to limit distortion from low duty cycle or burst mode data High noise immunity Compatible with Avago's versatile link family of connectors, for easy termination of fiber HFBR-0508Z links operate from DC to 10 MBd at distances up to 50 meters with 1 mm POF and up to 500 meters with 200 m HCS. No minimum link distances are required when using recommended circuits, simplifying design. Versatile Link components can be interlocked (N-plexed together) to minimize space and to provide dual connections with the duplex connectors. Up to eight packages can be interlocked and inserted into a printed circuit board. POF and HCS are available in pre-connectored lengths or can be easily field-terminated. A single transmitter drive current for POF and HCS allows both fibers to be used with a single design. Applications Industrial control and factory automation Serial field buses Intra-system links; board-to-board, rack-to-rack Extension of RS-232, RS-485 Elimination of ground loops High voltage isolation Reduces voltage transient susceptibility HCS is a registered trademark of OFS. CAUTION: It is advised that normal static precautions be taken in handling and assembly of these components to prevent damage and/or degradation which may be induced by ESD.

The IC includes a unique circuit to correct the pulse width distortion (PWD) of the first bit after a long idle period. This enables operation from DC to 10 MBd with low PWD for arbitrary data patterns. The receiver output is a "push-pull" stage compatible with TTL and CMOS logic. The receiver housing is a dark, conductive plastic, compatible with all Versatile Link connectors. 4 3 IC PRL,min Peak POF Overdrive Limit:Maximum Input for Logic "0" PRL,max Peak POF Off State Limit: Maximum Input for Logic "1" PRH,max Peak HCS Sensitivity: Minimum Input for Logic "0" PRL,min Peak HCS Overdrive Limit: Maximum Input for Logic "0" PRL,max Peak HCS Off State Limit: Maximum Input for Logic "1" PRH,max -23.0 +1.0 +0.0 -1.0 +5.0 -25.0 -1.0 -2.0 -3.0 -21.0 -20.0 -19.5 19 GROUND 1 VO SEE NOTES 5,7 HFBR-2528Z Receiver, top view Note Fig. dBm +25 0 to +70 -40 to +85 1 mm POF, |PWD| < 30 ns 2,6 8,10 dBm +25 0 to +70 -40 to +85 1 mm POF, |PWD| < 30 ns 2,3, 6 7,8, 9 1 mm POF 2,6, 8 -42 dBm -23.0 -22.0 -21.5 dBm +25 0 to +70 -40 to +85 200 m HCS, |PWD| < 30 ns 2,6 dBm +25 0 to +70 -40 to +85 200 m HCS, |PWD| < 30 ns 2,3, 6 200 m HCS 2,6, 8 +3.0 -44 dBm 45 mA VO = Open V IO = -40 A Supply Current ICC High Level Output Voltage VOH Low Level Output Voltage VOL 0.22 0.4 V IO = +1.6 mA Output Rise Time tr 12 30 ns CL = 10 pF 6 Output Fall Time tf 10 30 ns CL = 10 pF 6 Thermal Resistance, Junction to Case jc 200 C/W Electric Field Immunity EMAX 8 V/m Near Field, Electrical Field Source 5 Power Supply Noise Immunity PSNI 0.4 Vpp Sine Wave DC - 10 MHz 6 4.2 0.1 4.7 VCC 2 GROUND 8 Electrical and Optical Characteristics: TA = -40 to +85C, 4.75 V < VCC < 5.25 V, unless otherwise noted.
