By Maxim Integrated 18
Maxim Integrated's DS4830 provides a complete optical control, calibration, and monitor solution with a low-power, 16-bit, MAXQ20 microcontroller core providing generous program and RAM data memory. I/O resources include a fast/accurate analog-to-digital converter (ADC), fast comparators with an internal comparison digital-to-analog converter (DAC), 12-bit DACs, 12-bit PWMs, internal and external temperature sensors, fast sample/hold, I2C slave host interface, and a multiprotocol serial master/slave interface. Direct connection of diode-connected transistors, used as remote temperature sensors, is supported as well as expansion to a virtually unlimited number of external digital temperature sensor ICs using the on-chip master I2C interface. An independent slave I2C interface facilitates communication to a host microprocessor in addition to password-protected in-system reprogramming of the on-chip flash.
Ease of development is supported with highly versatile C-compilers and development software that programs flash and performs in-circuit debug through the integrated JTAG interface and associated hardware.
The DS4830 optical microcontroller is ideal for applications such as optical transceivers, including XFP, SFP, SFP+, QSFP, 40G, 100G and PON diplexers and GPON, 10GEPON, XPON OLT, and ONU triplexers.
