Application Notes
Transmitter: When the DATA+ input is at logic HIGH and be well-filtered. All 0.1 µF power supply bypass capacitors
DATA- input is at logic LOW, the LD is ON; and vice versa. should be as close to the DTR transceiver module as possible.
In single-ended applications, the unused input pin should be The two front GND posts should be grounded to Circuit
biased to V - 1.29 V.

The transmitter incorporates an Average Power Control
(APC) loop to stabilize the transmitter average optical output
power against temperature variation. The APC loop always
acts to keep the transmitter average optical output

the Transmitter should be close to the DTR transceiver
module. The termination resistors for the Receiver should
be close to the PHY or SERDES device (which receives the
DATA outputs from the Receiver).

Receiver: Both differential DATA+ and DATA-
outputs are PECL levels requiring termination (50
ohms to VCC - 2 volts or 160 ohms to GND is
recommended). For optimum performance, both
outputs should be terminated in the same manner,
even if only one is used.
The Signal Detect circuit monitors the level of
the incoming optical signal and generates a logic
LOW signal when insufficient photocurrent is
produced. The SIGNAL DETECT output is
LVTTL and do not need any termination.
