V23818-N15-L616 Datasheet, PDF (3/20 Pages) Infineon Technologies AG – Small Form Factor Single Mode 1300 nm Multirate up to 2.5 Gbit/s Transceiver 2x10 Pinning with LC™ Connector, with Collar

V23818-N15-L6xx
V_EEr / V_EEt
Connect pins 2, 3, 6, 12 and 16 to signal ground.
Pin Configuration
V_CCr / V_CCt
A 3.3 V DC power supply must be applied at pins 7 and 11. 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-N15-L653/L656 terminated and AC
coupled internally. For V23818-N15-L616 use termination and coupling as shown in the
termination scheme.
RD– / RD+
Receiver data LVPECL level outputs. For V23818-N15-L653/L656 biased and AC
coupled internally. For V23818-N15-L616 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-N15-L653/L656. LVPECL output for V23818-N15-L616.
A logical high output indicates normal optical input levels to the receiver. Low optical
input levels at the receiver result in an LVTTL 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.
