The TZA3031AHL, TZA3031BHL and TZA3031U are fully integrated laser drivers for STM1/OC3 (155 Mbits/s) systems, incorporating the RF path between the data multiplexer and the laser diode. Since the dual loop bias and modulation control circuits are integrated on the IC, the external component count is low. Only decoupling capacitors and adjustment resistors a.
• 155 Mbits/s data input, both Current-Mode Logic (CML) and Positive Emitter Coupled Logic (PECL) compatible; maximum 800 mV (p-p)
• Adaptive laser output control with dual loop, stabilizing optical ONE and ZERO levels
• Optional external control of laser modulation and biasing currents (non-adaptive)
• Automatic laser shutdown
• Few external components required
• Rise and fall times of 120 ps (typical value)
• Jitter <50 mUI (p-p)
• RF output current sinking capability of 60 mA
• Bias current sinking capability of 90 mA
• Power dissipation of 430 mW (typical value)
• Low cost LQFP32 plastic p.
