OUTPUT LOAD
Data Sheet
Figure 26. Receiver Input Eye Diagram Jitter Mask
The S2004 serial outputs do not require output pull-
down resistors.
Bit Time
Acquisition Time
With the input eye diagram shown in Figure 25, the
S2004 will recover data with a ≤1E-9 BER within the
Amplitude
time specified by T
in Table 28 after an instanta-
LOCK
neous phase shift of the incoming data.
