The MPC92433 is a 3.3 V compatible, PLL based clock synthesizer targeted for high
performance clock generation in mid-range to high-performance telecom, networking, and
computing applications. With output frequencies from 42.50 MHz to 1428 MHz and the
support of two differential PECL output signals, the device meets the needs of the most
demanding clock applications.

The MPC92433 is a programmable high-frequency clock source (clock synthesizer). The internal PLL generates a high-frequency
output signal based on a low-frequency reference signal. The frequency of the output signal is programmable and can be changed on the
fly for frequency margining purposes.
The internal crystal oscillator uses the external quartz crystal as the basis of its frequency reference. Alternatively, a LVCMOS
compatible clock signal can be used as a PLL reference signal. The frequency of the internal crystal oscillator is divided by a selectable
divider and then multiplied by the PLL. The VCO within the PLL operates over a range of 1360 to 2856 MHz. Its output is scaled by a
divider that is configured by either the I2C or parallel interfaces. The crystal oscillator frequency fXTAL, the PLL pre-divider P, the feedback-
divider M, and the PLL post-divider N determine the output frequency. The feedback path of the PLL is internal.
The PLL post-divider N is configured through either the I2C or the parallel interfaces, and can provide one of seven division ratios (2,
4, 6, 8, 12, 16, 32). This divider extends the performance of the part while providing a 50
duty cycle. The high-frequency outputs, QA
and QB, are differential and are capable of driving a pair of transmission lines terminated 50 to
VCC – 2.0 V. The second high-frequency output, QB, can be configured to run at either 1x or 1/2x of the clock frequency or the first output
(QA). The positive supply voltage for the internal PLL is separated from the power supply for the core logic and output drivers to minimize
noise induced jitter.
The configuration logic has two sections: I2C and parallel. The parallel interface uses the values at the M[9:0], NA[2:0], NB, and P
parallel inputs to configure the internal PLL dividers. The parallel programming interface has priority over the serial I2C interface. The
serial interface is I2C compatible and provides read and write access to the internal PLL configuration registers. The lock state of the PLL
is indicated by the LVCMOS-compatible LOCK output.
