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 7000.
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 maintained.
