Notes:
1. Absolute Maximum Ratings are those values beyond which damage to the device may occur if these limits are exceeded for other than a short
period of time. See Reliability Data Sheets for specific reliability performance.
2. Between Absolute Maximum Ratings and the Recommended Operating Conditions, functional performance is not intended, device reliability is
not implied, and damage to the device may occur over an extended period of time.

Notes:
1. Transmitter an d Receiver Ground are common in the internal module PCB. They are electrically connected to signal
ground within the module, and to the housing shield (see Note 5 in Figure 7c). This housing shield is electrically isolated
from the nose shield which is connected to chassis ground (see Note 4 in Figure 7c).
2. TX disable input is used to shut down the laser output per the state table below. It is pulled down internally within the
module with a 9.0 KW resistor.
Low (0 – 0.8 V):
Transmitter on
Between (0.8 V and 2.0 V):
Undefined
High (2.0 – 3.63 V):
Transmitter Disabled
Open:
Transmitter Enabled
3. SD (Signal Detect) is a normally high LVTTL output. When high it indicates that the received optical power is adequate
for normal operation. When Low, it indicates that the received optical power is below the worst case receiver sensitivity,
a fault has occurred, and the link is no longer valid.
4. RD-/+: These are the differential receiver outputs. They are AC coupled 100 W differential lines which should be
terminated with 100 W differential at the user SerDes. The AC coupling is done inside the module and is thus not
required on the host board. The voltage swing on these lines will be between 400 and 2000 mV differential (200 – 1000
mV single ended) when properly terminated. These levels are compatible with CML and LVPECL voltage swings.
5. V
CCR and VCCT are the receiver and transmitter power supplies. They are defined as 2.97 – 3.63 V at the PTH connector
pin. The maximum supply current is 200 mA.
