MAXIM MAX3632ETG

The MAX3632 burst-mode limiting amplifier is designed for 622Mbps or 1244Mbps GPON OLT receiver applications. It operates, together with the MAX3630/ MAX3631 burst-mode transimpedance amplifiers, to convert current from a photodiode into an LVPECL output signal. The MAX3632 contains a data input stage, a gain stage, an offset correction loop, a reset and hold section, and an LVPECL output buffer.

• The MAX3632 burst-mode limiting amplifier is designed specifically for 622Mbps or 1244Mbps GPON (G.984) optical line terminal (OLT) receiver applications.
• Together with the MAX3630/MAX3631 burst - mode transimpedance amplifiers (TIAs), a wide - dynamic - range burst - mode signal current (from a PIN or avalanche photodiode) can be translated to a differential LVPECL output.
• The MAX3632 has an electrical input sensitivity of 4mVP - P that supports GPON class - B optical sensitivity at 622Mbps with a PIN photodiode.
• An LVPECL - compatible burst reset input ((\overrightharpoon{\sf R S T})) connected to the limiting amplifier is used to control the offset correction loop of the MAX3632 as required for burst - mode operation, as well as to arm the threshold - setting circuitry of MAX3630/MAX3631 TIAs.
• The MAX3632 is available in a low - profile, (4\mathrm{mm}\times4\mathrm{mm}), 24 - lead thin QFN package.
• It operates from a single (+3.3V) power supply over a (-40^{\circ}\mathrm{C}) to (+85^{\circ}\mathrm{C}) temperature range.
