Pin Configuration
VCCr / VCCt
For 2x10 transceivers a 3.3 V DC power supply must be applied at pins 7 and 11. For
2x5 transceivers a 3.3 V DC power supply must be applied at pins 2 and 6. A
recommended power supply filter network is given in the termination scheme. Locate
power supply filtering directly at the transceiver power supply pins. Proper power supply
filtering is essential for good EMI performance.
TD+ / TD–
Transmitter data LVPECL level inputs. For V23818-K15-L47/L46/L57/L56/L45
terminated and AC coupled internally. For V23818-K15-L37/L36/L17/L16/L35 use
termination and coupling as shown in the termination scheme.
RD– / RD+
Receiver data LVPECL level outputs. For V23818-K15-L47/L46/L57/L56/L45 biased and
AC coupled internally. For V23818-K15-L37/L36/L17/L16/L35 use termination and
coupling as shown in the termination scheme.
TDis
A logical LVTTL high input will disable the laser. To enable the laser, an LVTTL low input
must be applied. Leave pin unconnected if feature not required.
SD
LVTTL output for V23818-K15-L47/L46/L57/L56/L45.
LVPECL output for V23818-K15-L37/L36/L17/L16/L35.
A logical high output indicates normal optical input levels to the receiver. Low optical
input levels at the receiver result in a low output. Signal Detect can be used to determine
a definite optical link failure; break in fiber, unplugging of a connector, faulty laser source.
However it is not a detection of a bad link due to data-related errors.
MS
Mounting studs are provided for transceiver mechanical attachment to the circuit board.
They also provide an optional connection of the transceiver to the equipment chassis
ground. The holes in the circuit board must be tied to chassis ground.
HL
Housing leads are provided for additional signal grounding. The holes in the circuit board
must be included and tied to signal ground.

Figure 9 Functional Diagram 2x5 Pin Rows
The receiver component converts the optical serial data into an electrical data (RD+ and
RD–). The Signal Detect output (SD) shows whether an optical signal is present.
The transmitter part converts electrical LVPECL compatible serial data (TD+ and TD–)
into optical serial data.
The module has an integrated shutdown function that switches the laser off in the event
of an internal failure.
Reset is only possible if the power is turned off, and then on again. (VCCt switched below
VTH).
The transmitter contains a laser driver circuit that drives the modulation and bias current
of the laser diode. The currents are controlled by a power control circuit to guarantee
constant output power of the laser over temperature and aging. The power control uses
the output of the monitor PIN diode (mechanically built into the laser coupling unit) as a
controlling signal, to prevent the laser power from exceeding the operating limits.
