Configuring the MK1716-01
Initial State: The MK1716-01 may be configured to have up to nine frequency outputs, utilizing a single PLL and
on-board spread spectrum circuitry. Unprogrammed, the part has the following outputs, related to the reference
input clock:
The STROBE pin must have an external 250 kOhm pull-up resistor to acheive the Initial State.
The input crystal range for the MK1716-01 is 5 MHz to 27 MHz.
The MK1716-01 can be programmed to set the output functions and frequencies. 160 data bits generated by the
VersaClockTM software are written in DATA pin in this order: MSB (left most bit) first.
As show in Figure 2, after these 160 bits are clocked into the MK1716-01, taking STROBE high will send this data
to the internal latch and the CLK output will lock within 10 ms.
Note: STROBE utilizes a transparent latch that is latched when in the high state. If STROBE is in the high state and
SCLK is pulsed, DATA is clocked directly to the internal latch and the output conditions will change accordingly.
Although this will not damage the MK1716-01, it is recommended that STROBE be kept low while DATA is being
clocked into the MK1716-01 in order to avoid unintended changes on the output clocks.
