Functional Description

The MPC92432 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 purpose.

The internal crystal oscillator uses the external quartz crystal as the basis of its frequency reference. Alternatively, a LVCMOS com-

patible 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 2720 MHz. Its output is scaled by

a divider that is configured by either the I²C or parallel interfaces. The crystal oscillator frequency f_XTAL, 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 six division ratios (2,

4, 8, 16, 32, 64). This divider extends the performance of the part while providing a 50% duty cycle. The high-frequency outputs, Q_A

and Q_B, are differential and are capable of driving a pair of transmission lines terminated 50 Ω to V_CC– 2.0 V. The second high-fre-

quency output, Q_B, can be configured to run at either 1x or 1/2x of the clock frequency or the first output (Q_A). 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 outputs.
