The ABMJB-902-155USY-T5 clock generator is a fractional-N synthesizer multifunction chip that can produce various types of clock and timing signals. This device can generate several programmable output clocks with different frequencies, automatically select different frequency bands, power down itself, and adjust its operating parameters by using an external serial interface (SPI).

It is a standard BGA15-pin device. It has two functional areas: one is the voltage controlled oscillator (VCO) unit and the other is the frequency synthesizer unit. The VCO unit includes a low noise charge pump and a wide range VCO core, which can reduce the noise. The frequency synthesizer unit includes a fractional-N synthesizer, a phase/frequency detector (PFD), and a loop filter. It can generate different frequencies, multiply or divide these frequencies, adjust the duty cycle of the output clock, and downscale the output voltage.

Its application fields are in-system clock generation, radio frequency (RF) signaling, and remote control. Its working principle is that when the chip is powered, the input reference clock is first sent to the PFD and the fractional-N synthesizer, and then goes through the loop filter in order to get the modulation and wide range of VCO. The VCO then produces several output clocks with different frequencies. To adjust the output, a serial port clock (SPI) is connected to the control unit. By sending clock, control data and parameters, the user can make changes in the output frequencies, duty cycle, voltage level and so on.

The main benefits of using this clock generator are that it is low-cost, low-power, and has a low-noise filter which increases the clock accuracy. It can also provide reliable operations and excellent noise immunity. The various application fields and easy configuration makes this chip the ideal choice for clock generation, RF signaling, and remote control. It is widely used in industrial, automotive and consumer applications.
