I/O Structure
The MK1492 provides more functionality in a 28 pin package by using a
unique I/O technique. The device checks the status of all I/O pins during
power-up. This status (pulled high or low) then determines the frequency
selections and power down modes (see the tables on page 2). Within 10ms
after power up, the inputs change to outputs and the clocks start up. In the
diagrams to the right, the 33
resistors are the normal output
termination resistors. The 10k
resistor pulls low to generate a logic
zero. Internal pull-up resistors (approx. 100k
) are present on DS, SEL0,
FS, LE, CPUS#, PCISTP#, and CSSS. Internal resistors on PEN, SEL1,
and OE pull to a mid-level (M).
The CPUS# input should be connected as shown to implement the 0, M,
and 1 selections per the Power Down Control Table on page 2. Contact
MicroClock for suggested connections of PCISTP# if the PLL STOP
mode will be used.
