Module power consumption never exceeds 1W.
AC coupled.
Or open circuit.
Into 100 ohm diff erential termination.
20 – 80 %.
LOS is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.
All transceiver specifi cations are compliant with a power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specifi ed value
applied through the power supply fi ltering network shown on page 23 of the Small Form-factor Pluggable (SFP) Transceiver
MultiSource Agreement (MSA) 6, September 14, 2000. The Power Supply Rejection applies for a supply voltage range of 3.1 to
3.6 V.
Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ and Δ DJ.
For 8.5 Gbps operation, Jitter values for gamma T and gamma R are controlled by TDP and stressed receiver sensitivity.
