5 / 20 page 5 Avago Technologies Confidential Table 1. Absolute Maximum Ratings Stress in excess of any of the individual Absolute Maximum Ratings can cause immediate catastrophic damage to the module even if all other parameters are within recommended operating conditions. It should not be assumed that limiting values of more than one parameter can be applied to the module concurrently. Exposure to any of the Absolute Maximum Ratings for extended periods can adversely affect reliability. Parameter Symbol Min Max Units Reference Storage Temperature Ts -40 85 °C 3.3 V Power Supply Voltage Vcc -0.5 3.6 V Data Input Voltage – Single Ended -0.5 Vcc+0.5 V Data Input Voltage – Differential |Vdip - Vdin| 1.0 V 1 Control Input Voltage Vi -0.5 Vcc+0.5, 3.6 V Control Output Current Io -20 20 mA Relative Humidity RH 5 95 % Note 1. This is the maximum voltage that can be applied across the differential inputs without damaging the input circuitry. Table 2. 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 Recommended Operating Conditions, reliability is not implied and damage to the module may occur for such operation over an extended period of time. Parameter Symbol Min Typ Max Units Reference Case Temperature Tc 0 40 70 °C 1 3.3 V Power Supply Voltage Vcc 3.135 3.3 3.465 V Signal Rate per Channel 10.3125 GBd 2 Control* Input Voltage High Vih 2 Vcc+.3 V Control* Input Voltage Low Vil -0.3 0.8 V Two Wire Serial (TWS) Interface Clock Rate 400 kHz Power Supply Noise 50 mVpp 3 Receiver Differential Data Output Load 100 Ohms Fiber Length: to QSFP+ eSR4 (OM3/OM4) 0.5 300/400 m 4, 5 Fiber Length: to 10GBASE-SR (OM3/OM4) 0.5 300/400 m 4, 5 Fiber Length: to 40GBASE-SR4 (OM3/OM4) 0.5 100/150 m 4, 6 * Control signals, LVTTL (3.3 V) compatible Notes: 1. The position of case temperature measurement is shown in Figure 8. 2. 64b/66b coding is assumed 3. 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 Figure 9 for recommended power supply filter. 4. OM3 fiber is 2000 MHz·km 50µm MMF, and OM4 fiber is 4700 MHz·km 50µm MMF. 5. Channel insertion loss included with 1.5dB allocated for connection and splice loss. 6. Channel insertion loss included with 1.5dB (OM3) / 1dB (OM4) allocated for connection and splice loss. Table 3. Transceiver Electrical Characteristics* The following characteristics are defined over the Recommended Operating Conditions unless otherwise noted. Typical values are for Tc = 40°C, Vcc = 3.3 V Parameter Symbols Min Typ Max Units Reference Transceiver Power Consumption 1.5 W Transceiver Power Supply Current 475 mA Transceiver Power On Initialization Time tpwr init 2000 ms 1 * For control signal timing including ModSelL, LPMode, ResetL, ModPrsL, IntL, SCL and SDA see Control Interface Section. Note: 1. Power On InitializationTime is the time from when the supply voltages reach and remain above the minimum Recommended Operating Conditions to the time when the module enables TWS access. The module at that point is fully functional. |
