DECEMBER 15, 2008 -- Maxim Integrated Products (search for Maxim) has introduced the DS1875 PON/SFP controller and monitor. This device is designed to provide 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, Maxim asserts. 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). Maxim says the device 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 5 nsec. The receive power (RSSI) monitor provides 29 dB 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 degrees Celsius to +95 degrees Celsius temperature range. It is available in a 5x7-mm, 38-pin TQFN package. Pricing begins at $2.50 (10,000-up, FOB USA).
