Fiber Optic Components High-speed TTL Receiver HFD7000-2XX Series FEATURES • Designed to meet industrial LAN Local Area Network specifications • Converts optical input into an electrical signal • Typical sensitivity at 660 nm is -21 dBm • Single 5 V supply • High-speed dc to 16 Mbps • Metal SMA barrel for high mechanical stability • Separate grounding of the barrel provides excellent RFII/EMI/ESD shielding • Low-cost plastic version HFD7000-212 available • PIN-compatible with Honeywell’s HFD3403 5 Mbps receiver 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 comparator 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 dyanmic 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, the HFE For maximum performance of this receiver, a µF capacitor must be mounted between Vcc and ground no more than 3,0 mm in] away from the housing. A resistor in series with Vcc increases the filter’s performance. This minimizes external noise and allows the maximum sensitivity to be maintained. WARNING PERSONAL INJURY DO NOT USE these products as safety or emergency stop devices, or in any other application where failure of the product could result in personal injury. Failure to comply with these instructions could result in death or serious injury. WARNING MISUSE OF DOCUMENTATION • The information presented in this product sheet is for reference only.

Sensing and Control Fiber Optic Components High-speed TTL Receiver HFD7000-2XX Series OPERATION Optical power photons from the fiber strikes the active area of the photodiode and is converted to an electrical signal. The current is then converted to a voltage in the transimpedance pre-amplifier. The controlled gain limits the light current created by the photodiode in both the transimpedance pre-amplifier and in the post-amplifier. This avoids a possible overcharge of the amplifier and assures optimum PWD performance. The signal is compared with a threshold defining the system’s sensitivity limit. A final buffer provides a TTL output. The level sensitive behavior makes the system robust with respect to the external interference e.g. current/voltage spikes . The regulator supplies the entire system to ensure high rejection of power supply noise. ABSOLUTE MAXIMUM RATINGS 25 ºC [77 ºF] free air temperature unless otherwise noted.
