MPC9772FA is a clock generator device from Freescale Semiconductor. It is a single chip Clock Generator and Clock Source used for the production of different types of clocks, usually in applications where small size, low cost and low power consumption are required. It is a programmable Clock Generator and Clock Source that can generate very accurately timed reference signals and can also generate multiple on-board clocks.

MPC9772FA is based on a highly integrated PLL design that makes it suitable for a wide range of applications. The device includes an internal oscillator, a low noise PLL and a programmable frequency synthesis block. It is highly reliable and features low jitter. Due to its low jitter characteristics it is suitable for high performance applications.

MPC9772FA can be used for a wide range of clock generation and clock source applications. It can be used for the generation of very accurate on-board clock signals, for the generation of multi-phase clocks, for driving and controlling multiple off board devices and for clock synchronization. The device also supports clock switching, phase shifting and frequency synthesizing. It is widely used in clock generation and clock synchronization applications for mobile devices, industrial automation, medical devices and automotive markets.

The working principle of the device is based on the phase locked loop (PLL) technology. The device is designed to accept a low frequency input and generate an output clock signal with more accurate timing. The PLL consists of a phase detector, a Reference Frequency Synthesizer, a Charge Pump, and a Voltage-Controlled Oscillator (VCO). The phase detector compares the input clock and reference signals and, if a difference is found, a charge is sent to the charge pump to update the oscillator frequency so that the output stays in lock with the input reference.

The device is highly configurable, with features such as programmable duty cycle, output clock duty cycle, and clock output drive strength. Additionally, the output clock frequency can be set with a software programmable prescaler and selection of the desired output clock frequency is also supported. This allows for the same device to generate different types of clock signals that are necessary for a particular application.

MPC9772FA is one of the most widely used clock generator devices, due to its popularity in applications where low cost, small size and low power consumption are required. Its ability to generate stable, low jitter clocks, as well as its flexibility to generate multiple on-board and off-board clocks make it the ideal choice for a wide range of applications.
