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
differential excitation).
3. The specified input voltage range is the guaranteed and tested range for proper operation; BER < 1
1010.
4. An input sensitivity of 7 mV (p-p) for BER < 1
1010 is guaranteed. The typical input sensitivity for BER < 1 1010
is 2.5 mV (p-p).
5. CML inputs are terminated internally using on-chip resistors of 50
connected to ground.
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
pins COUT to DOUT or pins CLOOP to DLOOP. It should be noted that small deviations of the specified value are
possible if measured differentially.
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
guaranteed.
11. Measured in accordance with ITU specification G.958. Measured on demoboard OM5801 for STM16/OC48 and
demoboard OM5802 for STM1/OC3 and STM4/OC12. See for more information
“Application note AN96051” and
“Application note AN97065”.
12. Measured in accordance with ITU specification G.813 and 1 dB above the system input sensitivity power level.
Measured on demoboard OM5801 for STM16/OC48 and on demoboard OM5802 for STM1/OC3 and STM4/OC12.
13. TDR is bit rate independent.
