Notes
1. Typical power supply voltage for the voltage regulator is 4.5 V (see Fig.6).
2. It is assumed that both CML inputs carry a complementary signal with the specified peak-to-peak value (true
3. The specified input voltage range is the guaranteed and tested range for proper operation; BER < 1 10
4. An input sensitivity of 7 mV (p-p) for BER < 1 10
5. CML inputs are terminated internally using on-chip resistors of 50
6. Output voltage range with default reference voltage on pin AREF (floating).
7. Output voltage range with adjustment of voltage on pin AREF (see Section “Output amplitude reference”).
8. Measured with 1010 data pattern, single-ended output signals and rising edges of the signals on
9. External pull-up resistor of 10 k connected to supply voltage of +3.3 V.
10. LOS assert or de-assert timing and BER level are for indication only. The values are neither production tested nor
11. Measured in accordance with ITU specification G.958. Measured on demoboard OM5801 for STM16/OC48 and
12. Measured in accordance with ITU specification G.813 and 1 dB above the system input sensitivity power level.
13. TDR is bit rate independent.
