HFM1300
Ethernet Receiver
APPLICATION
(continued)
The open collector output (PKT) indicates presence of a
valid Ethernet packet. This output goes low following the
first two data edges that are 200 ns or less apart at the
start of a packet. It returns high before the end of the
first half cycle of a valid 1 MHz idle signal.
The HFM1300 is designed to operate with a 12 V supply
(normally present in FOIRL interfaces and personal
computer backplanes). The module requires a minimum
+8.5 V total voltage. If a +12 V supply is not available,
+5 V to V
pin and -5 V to GND pin will operate the
module. Since the outputs are typically AC coupled, this
voltage shift is generally not a problem.
The HONEYWELL HFM1300 module is designed to
work with SINGLEMODE fibers. Final testing is
performed with 10 m 9/125
μ
m fiber.
