2. Over temperature and Beginning of Life.
3. MSA filter is required on host board 10 Hz to 1 MHz. See Figure 3
4. LVTTL, External 4.7 - 10 K: Pull-Up Resistor required
5. LVTTL, Internal 4.7 - 10 K: Pull-Up Resistor required for TX_Disable
6. Internally ac coupled and terminated (100 Ohm differential)
7. Internally ac coupled and load termination located at the user SerDes
8. Contributed DJ is measured on an oscilloscope in average mode with 50% threshold and K28.5 pattern
9. Contributed total jitter is calculated from DJ and RJ measurements using TJ = RJ + DJ. Contributed RJ is calculated for 1x10-12 BER by multiply-
10. Per IEEE 802.3

Notes:
1. Class 1 Laser Safety per FDA/CDRH
2. In conformance with FC-PI Figure 18, which defines allowable trade-off between wavelength, spectral width and OMA.

POUT TX_DISABLE Asserted
ing the RMS jitter (measured on a single rise or fall edge) from the oscilloscope by 14. Per FC-PI (Table 9 - SM jitter output, note 1), the actual
contributed RJ is allowed to increase above its limit if the actual contributed DJ decreases below its limits, as long as the component output DJ
and TJ remain within their specified FC-PI maximum limits with the worst case specified component jitter input.
