Failure to ply with these instructions could result in death or serious injury. DESCRIPTION The HFD7000 series are high-speed optical receivers designed for data transmission in industrial LAN applications. The monolithic CMOS chip consists of a large area photodiode, pre-amplifier with controlled gain, a post amplifier, a parator, and TTL output stage. The integrated voltage regulator provides easy use in many applications. The chip’s silicon material is optimized for 660 nm operation. The on-chip controlled gain provides a wide dynamic range and low pulse-width distortion (PWD). The chip is mounted in a metal TO-18 package. In addition, the outer package of the HFD7000-202 has a metal barrel for high mechanical stability and excellent shielding against RFI/EMI and ESD. This feature allows the receiver to operate in harsh environments. The receiver is designed to work with Honeywell’s high-speed 660 nm transmitter, HFE 7000. TYPICAL APPLICATIONS For maximum performance of this receiver, a 0.1 µF capacitor must be mounted between Vcc and Ground no more than 3,0 mm [0.12 in] away from the housing. A 4.7 Ω resistor in series with Vcc increases the filter’s performance. This minimizes external noise and allows the maximum sensitivity to be...
