DESCRIPTION
OPTICAL MODULES
Several generations of Silicon Labs MCUs have been developed to operate
at the heart of optical transceiver modules and are in full production in
millions of optical modules today. Their popularity in this application is
due to the combination of the high speed CPU and integrated precision
analog peripherals in the industry’s smallest packages. All required
system functions – such as oscillator, flash EEPROM and temperature
sensor – have been integrated into the MCU so that no additional external
components are required.

Microcontrollers
Silicon Labs MCUs that are widely used in
optical modules are shown in the diagram. In
addition there are many more options with CPU
speeds up to 100 MIPS, memory sizes up to 128
K bytes of flash EEPROM and package sizes
down to 2 mm x 2 mm. A hardware 16 x 16 MAC
(multiply-and-accumulate) module is available
on many of the MCUs to assist with complex
math requirements.
All Silicon Labs MCUs share the same proven
development environment and they are all
software compatible. There is also significant
hardware compatibility, in many cases designers
can drop in a higher or lower memory sized
version to optimize cost based on the firmware
requirements of the system.
