Notes:

1.

Voltage swing is specified as single-ended mVpp.

2.

Imposed for jitter performance.

3.

Rise and fall times can be estimated using the following simplified equation: tr/tf80-20 = ((0.8 – 0.2) x VIN_Vpp_se) / SR

4.

This mode is intended primarily for single-ended LVCMOS input clocks < 1 MHz that must be dc-coupled because they

have a duty cycle significantly less than 50%. A typical application example is a low-frequency video frame sync pulse.

Since the input thresholds (VIL, VIH) of this buffer are non-standard (0.33 and 0.49 V, respectively) refer to the input

attenuator circuit for dc-coupled pulsed LVCMOS in the Family Reference Manual at: www.silabs.com/

Support%20Documents/TechnicalDocs/Si5345-44-42-RM.pdf. Otherwise, for standard LVCMOS input clocks, use the

Standard Differential or Single-Ended ac-coupled input mode.
