(SDT8018-T_-Q_)
Specification : TS-S97D010E
Nov, 1999
5. Absolute Maximum Ratings
6. Electrical Interface
( Unless otherwise specified, Vcc-Vee = 4.75 to 5.25 V @2488.32Mbps, PRBS2^23-1, 50% duty
and all operating temperature shall apply.)
Warning
Use the product with the rated voltage described in the specification. If the voltage exceeds the maximum rating, overheating or fire
may occur.
Caution
Do not store the product in the area where temperature exceeds the maximum rating, where there is too much moisture or damp-
ness, where there is acid gas or corrosive gas, or other extreme conditions. Otherwise, failure, overheating or fire may occur.
1. Termination current is not included. 2. Measured between each signal input and VTTD or VTTC. Refer to Figure 3.
3. Refer to Figure 4. 4. Default (Open) normal operation. 5. Default (Open) clocked mode. 6. Alarm will be launched when LD bias
current exceeds 70mA typ. 7. LD bias current can be monitored by measuring the voltage difference between BM(+) Pin 22 and BM(-) Pin
21. Please refer to Figure 5.
8. Rear Facet PD current can be monitored by measuring the voltage difference between RFM(+) Pin 3 and
RFM(-) Pin 4. Please refer to Figure 5.
9. High input impedance ( > 1M
Ω) device is required to measure this voltage.
