MK1493-05GILFTR is a type of clock/timing application specific integrated circuit (ASIC). It is based on CMOS technology, employing a Dual-channel Frequency Synthesizer (DFS) design. The primary purpose of the chip is to provide an on-chip, programmable-frequency generation solution, allowing for extremely accurate time/clock signals to be generated. The outputs of the chip are designated as ‘P’, ‘Q’, ‘R’ and ‘S’ and their functions are as follows:

P – This output is the ‘master clock’ signal and is the highest frequency of the four signals. This is the output that is used to provide the master clock signals to the various parts of the circuit.

Q – This output is used to clock the memory devices in the circuit. It has a lower frequency than the ‘P’ output. This ensures that the data retention time for the memory devices is adequate.

R – This output is used to generate timing signals that are used to control the operation of command and control logic in the circuit. It is the lowest frequency of the four outputs. This is to guarantee that the data signals have enough time to be processed by the control logic.

S – This output is used to generate high-accuracy timing pulse signals, which are used as reference points for the operation of the circuit. The duty cycle of the output is 50% so that the signals generated by this output are also used to achieve synchronization between components of the circuit.

The frequency of the output signals generated by the chip can be set using an external resistor and capacitor. The output frequency is restrained and the orientation of the capacitor and resistor is controlled by the logic circuit on the chip. This allows the designer of the system to set the frequency of the output signals and control the speed of the circuit.

The chip can be used in a variety of applications including oscillators, phase-locked loops, and delay locked loops. The frequency of the output signals can be prorated depending on the application making the chip quite versatile. Additionally, the frequency accuracy of the chip is very high, which makes it ideal for timing critical applications. The chip can also be combined with other ASICs and digital logic integrated circuits (ICs) to create complex and reliable timing solutions. The on-chip logic allows the signals generated by the chip to be synchronized with the other components of the circuit.

Overall, the MK1493-05GILFTR is an extremely versatile and reliable clock/timing ASIC that can be used in a variety of applications. The frequency of the output signals can be easily set by the user and the accuracy is extremely high. Additionally, the chip can be combined with other ICs and ASICs without much difficulty, allowing for complex timing solutions to be created. Due to its high level of versatility and reliability, the chip is a popular choice for many timing applications.
