Applications
Description
The Si5013 is a fully-integrated, high-performance limiting amplifier (LA)
and clock and data recovery (CDR) IC for high-speed serial
communication systems. It derives timing information and data from a
serial input at OC-12/3 and STM-4/1 rates. Use of an external reference
clock is optional. Silicon Laboratories DSPLL
sensitive noise entry points, thus making the PLL less susceptible to
board-level interaction and helping to ensure optimal jitter performance.
The Si5013 represents a new standard in low jitter, low power, small size,
and integration for high-speed LA/CDRs. It operates from a 3.3 V supply
over the industrial temperature range (–40 to 85 °C).

... PLL the acquisition time, and maintains a stable output clock (CLKOUT) when lock-to-reference (LTR) is asserted. When the reference clock is present, the Si5013 uses the reference clock to center the VCO output frequency so that clock and data is recovered from the input data stream. The device self configures for operation with one of three reference clock frequencies ...

... This produces a stable output clock as long as supply and temperature are constant. 4.8. Loss-of-Signal (LOS) The Si5013 indicates a loss-of-signal condition on the LOS output pin when the input peak-to-peak signal level on DIN falls below an externally controlled threshold. The LOS threshold range is specified in Table 3 on page 8 and is set by applying a voltage on the LOS_LVL pin ...
