10 Gb/s Small Form-Factor Detector + TIA
Receiver Optical Sub-Assemblies (ROSAs)
Product Brief
Description
The 1640 and 1641 -Type 10 Gb/s receiver optical subas-
sembly (ROSA) integrates a 10 Gb/s APD or PIN photode-
tector and a transimpedance amplier (TIA) in a metal/
ceramic package. These receiver optical engines are de-
signed for use in transceivers and transponders for high-
speed data and telecommunications applications.

• 300-pin transponders, LFF and SFF
Features
• Up to 11.3 Gb/s data-rate capability
• –28 dBm typical sensitivity (APD version)
• –20.5 dBm typical sensitivity (PIN version)
• 12 kW typical dierential transimpedance gain
• Flat group delay
• 3.3V single power supply
• LC receptacle
• Wide operating temperature range: -5 to +85°C

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those
given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can
adversely aect device reliability.

Notes:
1. VBR = breakdown voltage, dened at IDARK = 10 mA.
2. Based on human-body model of R = 1500 W and C = 100 pF. In general, ESD precautions should be taken to avoid damage to the device.
3. Requires external current-limiting circuit to meet the stated rating for reverse current.

Electrostatic Discharge
CAUTION: This device is susceptible to damage as a result of electrostatic discharge. Take proper precautions
during both handling and testing. Follow guidelines such as JEDEC Publication No. 108-A (Dec. 1988).
Avago Technologies employs a human-body model (HBM) for ESD-susceptibility testing and protection-design
evaluation. ESD voltage thresholds are dependent on the critical parameters used to dene the model. A stan-
dard HBM (resistance = 1.5 kW, capacitance = 100pF) is widely used and can be used for comparison purposes.

Notes:
1. The eye crossing level will be nominally ~50% if Vcr (pin2) is left oating, when the voltage at pin2 will be approximately Vcc - 0.5V. Vcr can be used
to adjust the eye crossing level during gain saturation, by sourcing or sinking a current at pin2, which has a typical input resistance of ~18kOhm.
An input current range of +/-15uA provides a full range of eye crossing adjustment.

Notes:
1. Optimum APD bias voltage (VOP) varies from device to device. The optimum value of VOP will be provided with each device.
2. The eye crossing level will be nominally ~50% if Vcr (pin2) is left oating, when the voltage at pin2 will be approximately Vcc - 0.5V. Vcr can be used
to adjust the eye crossing level during gain saturation, by sourcing or sinking a current at pin2, which has a typical input resistance of ~18kOhm.
