The monolithic CMOS (Complementary Metal-Oxide Semiconductor) 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 dynamic range and low PWD (Pulse Width Distortion). The chip is mounted in a metal TO-18 package. 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 HFE7000. For maximum performance of this receiver, a 0.1 F capacitor must be mounted between Vcc and ground no more than 3.0 mm [0.12 in] away from the housing. A 4.7 resistor in series with Vcc increases the filter's performance. This minimizes external noise and allows the maximum sensitivity to be maintained.

Failure to comply with these instructions could result in death or serious injury. Fiber Optic Components High-speed TTL Receiver GFD3500-002 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 C [77 F] free air temperature unless otherwise noted.)
