7 / 44 page Product Specification 02069-DSH-001-D Mindspeed Technologies™ 7 Mindspeed Proprietary and Confidential 1.5 Safety Logic Timing (VCC = 3.05 V to 3.55V or 4.7V to 5.5V, TA = -40 °C to +95 °C, unless otherwise noted) Typical values for common anode are at VCC = 3.3 V, IBOUTCA = 20 mA, IMOD = 20 mA, TA = 25 °C, unless otherwise noted. Typical values for common cathode are at VCC = 3.3 V, IBOUTCC = 5 mA, IMOD = 5 mA, TA = 25 °C, unless otherwise noted. tr Modulation output rise time 20% to 80% into 25 Ω(3). For I MOD from 3 mA to 30 mA. Measured using 11110000 pattern at 2.5Gbps. – 67 80 ps tf Modulation output fall time – 67 80 ps OSOFF Overshoot of modulation output current in the “off” direction into 25 Ω load -- 1 2 % RJ Random jitter – 0.8 – psrms DJ Deterministic jitter K28.5 pattern at 4.3 Gbps (includes pulse width distortion) 10 23 pspp Notes: 1. Minimum voltage at OUT+ > 0.7V. 2. The current through the laser in this state can be made negligible by adding a 1k Ω or less resistor in parallel with the laser. 3. The M02069 is designed to drive 25 Ω loads. External resistance should be added in series or parallel to the Laser to create this load impedance. In common cathode mode, 50 Ω resistors internal to the M02069 are in parallel with the laser.. Table 1-5. Safety Logic Timing Symbol Parameter Conditions Min. Typ. Max.
