Typical power supply voltage for the voltage regulator is
4.5 V (see Fig.6).
It is assumed that both CML inputs carry a complementary signal with the specified peak-to-peak value (true
differential excitation).
The specified input voltage range is the guaranteed and tested range for proper operation; BER < 1

In DCR mode, an input sensitivity of 7 mV (p-p) for BER < 1

is 2.5 mV (p-p). In bypass mode, full clipping of the output signal occurs at about 25 mV (p-p),
see Fig.15.
CML inputs are terminated internally using on-chip resistors of 50
connected to ground.
Output voltage range with default reference voltage on pin AREF (floating).
Output voltage range with adjustment of voltage on pin AREF (see Section “Output amplitude reference”).
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.
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 with demoboard OM5801 for STM16/OC48,
STM4/OC12 and STM1/OC3. See for more information “Application note AN96051”
12. Measured in accordance with ITU specification G.813 and 10 dB above the system input sensitivity power level.
Measured with demoboard OM5801 for STM16/OC48, STM4/OC12 and STM1/OC3.
13. TDR is bit rate independent.
