Jitter due to droop is proportional to the droop and

Fail-Safe  
The MAX9210/MAX9212/MAX9214/MAX9216/MAX9220/  
MAX9222 have fail-safe LVDS inputs in non-DC-bal-  
anced mode (Figure 1). Fail-safe drives the outputs low  
when the corresponding LVDS input is open, undriven  
and shorted, or undriven and parallel terminated. The  
fail-safe on the LVDS clock input drives all outputs low.  
Fail-safe does not operate in DC-balanced mode.

D = droop (% of signal amplitude).  
Jitter due to 2% droop and assumed 1ns transition time is:  
Input Bias and Frequency Detection  
In DC-balanced mode, the inverting and noninverting  
LVDS inputs are internally connected to +1.2V through  
42kΩ (min) to provide biasing for AC-coupling (Figure 1).  
A frequency-detection circuit on the clock input detects  
when the input is not switching, or is switching at low  
frequency. In this case, all outputs are driven low. To  
prevent switching due to noise when the clock input is  
not driven, bias the clock input to differential +15mV by  
connecting a 10kΩ 1% pullup resistor between the

The transition time in a real system depends on the fre-  
quency response of the cable driven by the serializer.  
The capacitor value decreases for a higher frequency  
parallel clock and for higher levels of droop and jitter.  
Use high-frequency, surface-mount ceramic capacitors.  
Equation 1 altered for four series capacitors (Figure 13) is:
