1. Must be externally AC coupled and externally loaded by 50
.
2. The OILV output is tested and tuned using a 1550 nm optical input. When a 1310 nm source is present, the OILV output may vary by ±2 dB since there may be an offset associated
with receiving a 1310 nm optical signal as compared to 1550 nm. However, typically most modules will exhibit a small variation between 1310 nm and 1550 nm inputs.
3. By varying the DTV voltage at pin 13 from 0.5 VDC to 3.5 VDC the quanitization threshold level is shifted from the bottom of the data eye to the top of the data eye respectively.
Threshold adjustment without optical noise (Voptimum) is symmetric about 2.0 VDC. At DTV set points of 0.5 VDC and 3.5 VDC, the BER will be shifted to a typical
value of 10 E-7 from a nominal BER of 10 E-10 (i.e. no input applied at DTV). If the DTV function is not required, pin 13 should be left open. An extended DTV full-
scale input range of 0.0 V to 5.0 V may be used if additional threshold adjustment range is required.
4. This requirement is only applicable when used with a CDR, which meets the given jitter tolerance and jitter transfer specifications.
