Industry's Most Integrated PON/SFP Controller with APD Boost Converter for Fiber Optic Modules
o The DS1875 is a highly integrated PON/SFP controller with an APD boost converter for fiber optic modules.
o This device simplifies the implementation, speeds the time to market, and minimizes the chip count of triplexer PON modules.
o To enable these benefits, the DS1875 features a state-machine design, which eliminates the need for software development. Additionally, the integrated APD boost converter reduces chip count.
o The DS1875 is ideal for PON triplexers, PON OLTs, and LR SFPs.
SUNNYVALE, CA-December 15, 2008-Maxim Integrated Products (NASDAQ: MXIM) introduces the DS1875 PON/SFP controller and monitor. This device provides all the control and monitoring features required for PON transceivers, as well as the monitoring features for video control in triplexer applications. The DS1875 employs a state-machine design, which eliminates the need for software development, thus simplifying design implementation and speeding time-to-market. Moreover, by integrating an APD boost converter, this device minimizes chip count in GPON applications. A complete monitoring solution, the DS1875 also integrates ten 13-bit ADC channels, six DAC channels, a temperature sensor, and 384 bytes of user EEPROM memory (SFF-8472 compliant). It is ideal for PON triplexers, PON OLTs, and LR SFPs.
The DS1875 also features a startup control loop that supports laser initialization in less than 5ns. The receive power (RSSI) monitor provides 29dB of dynamic range and programmable APD overload protection. DAC outputs for tracking error, laser bias, laser modulation, and APD bias are automatically adjusted based on lookup table values indexed in the internal temperature sensor. Quick-trip monitors are included for complete laser eye-safety protection.
The DS1875 is fully specified over the -40°C to +95°C temperature range. It is available in a tiny, 5mm x 7mm, 38-pin TQFN package. Pricing begins at $2.50 (10,000-up, FOB USA).
