DS4830
Optical Microcontroller
General Description
Features
The DS4830 provides a complete optical control, cali-
bration, and monitor solution with a low-power, 16-bit,
MAXQ20 microcontroller core providing generous pro-
gram and RAM data memory. I/O resources include
a fast/accurate analog-to-digital converter (ADC), fast
comparators with an internal comparison digital-to-ana-
log 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 micro-
processor 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 integrat-
ed JTAG interface and associated hardware.
Applications
PON Diplexers and Triplexers: GPON, 10GEPON,
XPON OLT, ONU
Optical Transceivers: XFP, SFP, SFP+, QSFP,
40G, 100G
