Product Details

The DS4830A is a low-power, 16-bit microcontroller with a unique peripheral set supporting optical applications that require high-resolution conversion of many analog signals and digital signal processing (DSP) of those signals, high-speed data communication to an external host, and ultra-low power dissipation. A wide variety of optical transceiver controller applications is supported without need of external circuitry, thereby minimizing cost and PCB area.

Power dissipation and throughput are optimized through the use of a programmable round-robin analog-to-digital converter (ADC) and 10-bit fast comparator, which operate completely independently of the core and significantly relieve core overhead. A dual multiply/accumulate (MAC) is included to minimize interrupt service timing/design complexity. Ten 16-bit PWM channels are included to provide an unprecedented level of precision in digital power-control applications.

The DS4830A provides a complete optical control, calibration, and monitor solution compatible with SFF-8472. Additional resources include a fast/accurate ADC, fast comparators with an internal comparison digital-to-analog converter (DAC), eight independent 12-bit DACs, an accurate internal temperature sensor, two fast sample/holds with various programmable options, and a multiprotocol serial master/slave interface. An independent, 400kHz-compliant, slave I2C interface with four configurable slave addresses facilitates communication to a host, in addition to password-protected in-system programming of the on-chip flash.

Extensive design-in and applications support are available, including comprehensive user’s and programmer’s guides, complete reference designs with documented code, and in-depth application notes showing numerous code examples in both C and assembly language. Firmware development is supported by third-party vendors.

Applications

  • Optical Transceivers: XFP, SFP, SFP+, QSFP+, CSFP, 40G, 100G
  • PON Diplexers and Triplexers: GPON, 10GEPON, XPON OLT, ONU
