Complete high-speed, low-power, CDR solution includes the following:
Applications
Description
The Si5020 is a fully-integrated low-power clock and data recovery (CDR)
IC designed for high-speed serial communication systems. It extracts
timing information and data from a serial input at OC-48/12/3, STM-16/4/1,
or Gigabit Ethernet (GbE) rates. Support for 2.7 Gbps data streams is also
provided for OC-48/STM-16 applications that employ forward error
correction (FEC). DSPLL technology eliminates sensitive noise entry
points, making the PLL less susceptible to board-level interaction and
helping to ensure optimal jitter performance.
The Si5020 represents a new standard in low jitter, low power, and small
size for high-speed CDRs. It operates from a single 2.5 V supply over the
industrial temperature range (–40 to 85 °C).
