Notes
1. For a bit error rate (BER) of less than 1x10^E–12 over a receiver eye
opening of least 1.5 ns. Measured with a 2⁷–1 PRBS at 194 MBd.
2. For a BER of less than 1x10^E-12. Measured in the center of the eye
opening with a 2⁷-1 PRBS at 194 MBd.
3. Measured at an average optical power level of –20 dBm with a
62.5 MHz square wave.
4. All jitter values are peak-to-peak. RX output jitter requirements are
not considered in the ATM standard draft. In general the same
requirements as for FDDI are met.
5. Measured at an average optical power level of –20 dBm.
6. Measured at –33 dBm average power.
7. An increase in optical power through the specified level will
cause the SIGNAL detect output to switch from a Low state to
a High state.
8. A decrease in optical power through the specified level will
cause the SIGNAL detect output to switch from a High state to
a Low state.
9. PECL compatible. Load is 50 Ω into V_CC –2 V. Measured under DC
conditions. For dynamic measurements a tolerance of 50 mV should
be added for V_CC=+5 V.

The power supply filtering is required for good EMI perfor-
mance. Use short tracks from the inductor L1/L2 to the module
V_CC–Rx/V_CC–Tx.
A GND plane under the module is recommended for good EMI
and sensitivity performance as well as ground connection of
studs.
