Limiting Amplifier with Integrated Laser Diode Driver
The TD2072 is a single chip integrated limiting postamplifier (LA) and laser diode driver (LD) for application in optical communication systems with operating data rates from 155Mbps to 1.25Gbps. The TD2072 is packaged in a small, 24-pin,4mm x 4mm thin QFN24L package, which is
unparalleled in the industry. It offers space savings of 50% or more over typical LA and LD.
The TD2072 operates from a single +3.3V±10% power supply, over temperature from -40°C to +85°C and consumes only 170mW (typical), exclusive of bias and modulation currents in LD and out put load in LA. The limiting post amplifier (LA) can detect signals with amplitude as low as 4mV PP . The
TD2072 quantizes these signals and outputs typically 800mV PP voltage-limited waveforms.
It incorporates two loss-of-signal (LOS) outputs, one is the open-collector LVTTL output with internal 5kΩ pull-upresistor and anotheris LVPECL output. A programmable loss-of-signal level set pin
(LOSLVL) sets the sensitivity of the input amplitude detection from the typical transimpedance amplifiers (TIAs).
The laser diode driver (LD) can deliver the modulation current up to 80mA and the bias current up to 80mA.
Its pin assignment is specially optimized for the application in 1X9 optical transceiver module and in SFP / SFF modules.
