and E3 inputs, CLK1 will be 1/2 the input frequency and CLK2 will be the same as the input frequency.
Buffer Mode
Unlike the other two modes that accept only a single specified input frequency, Buffer Mode will accept a wider range
of input clocks. The input jitter is attenuated, and the outputs on CLK1 and CLK2 also provide the option of getting
x1, x2, x4, or 1/2 of the input frequency. For example, this mode can be used to remove the jitter from a 27 MHz
clock, generating low-jitter 27 MHz and 13.5 MHz outputs.
INPUT AND OUTPUT SYNCHRONIZATION
As shown in the tables on pages 4 and 5, the MK2049-02/03 offer a Zero Delay feature in most selections. In these
selections, there is an internal feedback path between ICLK and the CLK2 output clock. This provides a fixed phase
relationship between the input and output, a requirement in many communications systems.
MK2049-02
As illustrated in the diagram below, when using the MK2049-02 in one of the Zero Delay selections, the rising edge
of ICLK will be aligned with the rising edge of CLK2. However, the CLK1 edge in these cases will be either rising or
falling. (8 kHz is used in this illustration, but the same is true for the Zero Delay selections in the Loop Timing and
Buffer modes.)
