Recommended Operating Conditions

Recommended Operating Conditions specify parameters for which the optical and electrical characteristics hold

unless otherwise noted. Optical and electrical characteristics are not defined for operation outside the Recommend-

ed Operating Conditions, reliability is not implied and damage to the module may occur for such operation over an

extended period of time.

Control signals, LVTTL (3.3 V) compatible, include Adr[2:0], IntL, ResetL, SCL and SDA.

1 The position for case temperature measurement is shown in Figure 11. Continuous operation at the maximum Recommended Operating Case

Temperature should be avoided in order not to degrade reliability. Modules will function (degraded performance may result) where operated with

case temperatures below the minimum Recommended Operating Case Temperature.

under test are operating with similar test patterns.

7. Power Supply Noise is defined as the peak-to-peak noise amplitude over the frequency range at the host supply side of the recommended power

supply filter with the module and recommended filter in place. Voltage levels including peak-to-peak noise are limited to the recommended

operating range of the associated power supply. See Figures 12 and 13 for recommended power supply filters.

8. For data pattern with restricted run lengths and disparity, e.g. 8b10b, smaller value capacitors may provide acceptable results.

9. Channel insertion loss includes 3.5 dB/km attenuation, 1.5 dB connector loss and 0.3 dB modal noise penalty allocations.
