M02139 1G/10G Gbps TIA with AGC and Rate Select The M02139 is a multi-rate TIA supporting data rates from 1 Gbps to 10.3 Gbps and having a wide input dynamic range to support different transmission distance requirements. Input overload of 2 mAPP and input sensitivity of better than -19 dBm are useful for single-mode, high power long haul links, as well as short haul multi-mode links. In order to satisfy such high sensitivity and good optical overload requirements, automatic gain control (AGC) is implemented in the M02139. The AGC monitors the output amplitude and automatically reduces the TIA gain when the photodiode current exceeds the AGC threshold, maintaining the output at a constant level. Requiring no extra pins on the ROSA, rate select is controlled by the DC potential on the mon pad. Low rate is optimized for 1G/1.25 Gbps performance with a typical sensitivity lower than -22 dBm. A replica of the average photodiode current is available at the MON pad for photo-alignment and SFF-8472 Rx power monitoring.

This achieves the best S/N ratio for optimum bit error rate performance of the incoming optical data stream. The noise performance of a TIA is a key specification for meeting the stringent optical sensitivity requirement. In general, the input referred noise calculations for a TIA are identical to those in other conventional amplifiers. The input referred noise can be determined from several methods. Traditionally at Mindspeed, TIA noise is obtained from dividing the output RMS voltage noise of the TIA by the transimpedance. The small signal transimpedance of the TIA can be calculated by applying a known p-p input current and then measuring the p-p differential output voltage. The equations used for IN (Input Referred Noise) and GTIA (Transimpedance) are shown below. The TIA output RMS noise can be measured conveniently by using a wide band oscilloscope (or by using a power meter and converting the noise power to noise voltage). IN = (VoutRMS / GTIA) GTIA = (VoutPP/ I_inputPP), where: IN = Input referred noise in RMS GTIA = TIA small signal transimpedance I_inputPP= p-p input current 1.1.2 Optical Input Sensitivity TIA input sensitivity can be calculated from the optical sensitivity equation directly based on the input referred noise, photodiode responsivity and transmitter extinction ratio information. Note that the Signal to Noise (S/N) must exceed 14.1 to achieve a system bit error rate (BER) of 1x10-12. Sensitivity = 10log {((S/N x IN x (ER + 1)) / (2 x ρ x (ER – 1))) x 1000} dBm Where: Sensitivity = Input sensitivity expressed in average power S/N = 14.1(for 10-12 BER) IN = Input Referred Noise in RMS ER = Extinction Ratio = 10 (typically) ρ = Photodiode Responsivity = 0.9 (typically) 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 3 Product Specification 1.2 Absolute Maximum Ratings These are the absolute maximum ratings at or beyond which the device can be expected to fail or be damaged.

Input overload of 2.0 mAPP is provided to support short-haul fiber optic systems. In order to satisfy such high sensitivity and good optical overload requirements, automatic gain control circuit (AGC) is implemented in the M02139. The AGC monitors the output amplitude and automatically reduces the TIA gain when the photodiode current exceeds the AGC threshold, maintaining the output at a constant level. A replica of the average photodiode current is available at the MON pad for photo-alignment and SFF-8472 Rx power monitoring. A low pass filter can be engaged by pulling IMON above 1.6 V, for 1.25 Gbps operation. Figure 3-1. M02139 Block Diagram MON Rf PINK BGAP AGC VREG Vreg Voltage Reg DOUT TIA PINA Gain Output Buffer DOUT DC Servo Current Ref Gen AGC 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 8 Functional Description 3.2 General Description 3.2.1 TIA (Transimpedance Amplifier) The transimpedance amplifier consists of a high gain single-ended amplifier (TIA) with a feedback resistor. The feedback creates a virtual low impedance at the input and nearly all of the input current passes through the feedback resistor defining the voltage at the output. Advanced design techniques are employed to maintain the stability of this stage across all input conditions. An on-chip low dropout linear regulator has been incorporated into the design to give excellent noise rejection up to several MHz. The circuit is designed for PIN photodiodes with the anode connected to the input of the TIA and the cathode connected to AC ground, such as the provided PINK terminal. Reverse DC bias is applied to reduce the photodiode capacitance. PIN photodiodes and Avalanche photodiodes may also be connected externally to a voltage higher than VCC. Care should be taken to correctly sequence the power supply to the externally biased photodiode so that the bias voltage does not appear when the TIA is powered down. Doing so may cause damage to the input of the TIA, as the photodiode bias can become capacitively coupled to the PIN input, and cause damage. 3.2.2 Output Stage The signal from the TIA enters a phase splitter followed by a DC-shift stage and a pair of voltage follower outputs. These are designed to drive a differential (100 Ω) load. They are stable for driving capacitive loads such as interstage filters. Each output has its own GND pad; it is recommended but not required that all four GND pads on the chip should be connected. Since the M02139 exhibits rapid roll-off (3 pole), no external filtering is necessary. 3.2.3 Offset Cancellation DC Servo Due to the high gain of the M02139 transimpedance amplifier, any amount of input offset voltage would be amplified and create distortion at the output. Therefore, an offset cancellation circuit is used to remove input offset. The RC offset cancellation circuit sets the low frequency cutoff to 50 kHz. 3.2.4 Monitor O/P and Rate Select Between 1G and 10G Operations The monitor is a high impedance output which sources an average photodiode current for alignment or power monitoring use. This output is mirrored off the PINK current source, and PINK must be used to enable IMON usage. If PINK is not used as in the case of externally biased PIN or APD detectors, then photo current must be monitored via that external bias supply and the MON pin tied to high or low depending on the input data rate. This output is compatible with the DDMI Receive Power Specification (SFP-8472). An interfacing example is shown below where the M02139 is connected to the M0217x driver family General Purpose I/O (GPIO) and Rx Power monitoring A/D. Ensure that the voltage on VMON is in the range of 0 to 2.0 V. Refer to Table 3-1 and Figure 3-2. Table 3-1. Selection of Rm for Maximum Input Current IIN Max (mA) Optical Power (dBm) Rm (Ω) 2 +3 500 1 0 1000 0.5 -3 2000 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 9 Functional Description For non-217X implementations, assume that the MON output would go into a resistor that is measured with a voltage ADC. That being the case, a voltage drop (diode or other) would need to be switched in and out to create the necessary voltage at the MON pin for both rate settings. The high impedance O/P source replicates the average photodiode current for monitoring purposes. The IMON pin can be also used to select between 1G and 10G operation. When the 1G mode is selected, the TIA output is filtered to reduce the bandwidth to 1G levels and hence improve sensitivity. The device is in low rate mode for Vmon greater than 1.6 V and in high rate mode for Vmon less than 1 V. The IMON feature can still be used under the 1G and 10G operations. Figure 3-2.

It is only necessary to bond one VCC pad and one GND pad. However, bonding both GND pads is encouraged for improved performance in noisy environments. The backside must be connected to the lowest potential, usually ground, with conductive epoxy or a similar die attach material. If a monitor output is not required then a 4 lead TO-Can may be used. 4.3 Treatment of PINK PINK does not require capacitor bypassing regardless of whether or not it is used to bias the photo diode. 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 12 Applications Information 4.4 T0-Can Assembly Recommendations Figure 4-3.

Many existing TO-Can configurations will not allow wirebond lengths that short, since the PIN diode submount and the TIA die are more than 1 mm away in the vertical direction, due to the need to have the PIN diode in the correct focal plane. This can be remedied by raising up the TIA die with a conductive metal shim. This will effectively reduce the bond wire length. Refer to Figure 4-3 on the previous page for details. Mindspeed recommends ball bonding with a 1 mil (25.4 µm) gold wire. For performance reasons the PINA pad has less via material connected to it. It therefore requires more care in setting of the bonding parameters. For the same reason PINA has limited ESD protection. In addition, please refer to the Mindspeed Product Bulletin (document number 0201X-PBD-001). Care must be taken when selecting chip capacitors, since they must have good low ESR characteristics up to 1.0 GHz. It is also important that the termination materials of the capacitor be compatible with the attach method used. For example, Tin/Lead (Pb/Sn) solder finish capacitors are incompatible with silver-filled epoxies. Palladium/Silver (Pd/Ag) terminations are compatible with silver filled epoxies. Solder can be used only if the substrate thick-film inks are compatible with Pb/Sn solders. 4.4.2 Recommended Assembly Procedures For ESD protection the following steps are recommended for TO-Can assembly: a. Ensure good humidity control in the environment (to help minimize ESD). b. Consider using additional ionization of the air (also helps minimize ESD). c. As a minimum, it is best to ensure that the body of the TO-can header or the ground lead of the header is grounded through the wire-bonding fixture for the following steps. The wire bonder itself should also be grounded. 1. 2. 3. 4. 5. 6. Wire bond the ground pad(s) of the die first. Then wire bond the VCC pad to the TO-Can lead. Then wire bond any other pads going to the TO-Can leads (such as DOUT, DOUT and possibly MON) Next wire bond any capacitors inside the TO-Can. Inside the TO-can, wire bond PINK. The final step is to wire bond PINA. 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 14 Applications Information 4.5 TIA Use with Externally Biased Detectors In some applications, Mindspeed TIAs are used with detectors biased at a voltage greater than available from TIA PIN cathode supply. This works well if some basic cautions are observed. When turned off, the input to the TIA exhibits the following I/V characteristic: Figure 4-4. TIA Use with Externally Biased Detectors, Powered Off PINA Unbiased 100 50 0 -800 -600 -400 -200 0 200 400 600 800 1000 1200 µA -50 -100 -150 -200 -250 -300 mV In the positive direction the impedance of the input is relatively high. 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 15 Applications Information After the TIA is turned on, the DC servo and AGC circuits attempt to null any input currents (up to the absolute maximum stated in Table 1-1) as shown by the I/V curve in Figure 4-5. Figure 4-5. TIA Use with Externally Biased Detectors, Powered On PINA biased 1000 800 600 400 µA 200 0 -300 -200 -100 0 100 200 300 400 500 600 700 -200 -400 -600 -800 -1000 mV It can be seen that any negative voltage below 200 mV is nulled and that any positive going voltage above the PINA standing voltage is nulled by the DC servo. The DC servo upper bandwidth varies from part to part, but is typically at least 50 kHz. When externally biasing a detector such as an APD where the supply voltage of the APD exceeds that for PINA Table 1-1, care should be taken to power up the TIA first and to keep the TIA powered up until after the power supply voltage of the APD is removed. Failure to do this with the TIA unpowered may result in damage to the input FET gate at PINA. In some cases the damage may be very subtle, in that nearly normal operation may be experienced with the damage causing slight reductions in bandwidth and corresponding reductions in input sensitivity. 02139-DSH-001-D Mindspeed Technologies® Mindspeed Proprietary and Confidential 16 5.0 Die Specification Figure 5-1.
