Functional Description

FA SUFFIX

32 LEAD LQFP PACKAGE

CASE 873A

The internal crystal oscillator uses the external quartz crystal as the

basis of its frequency reference. The frequency of the internal crystal

oscillator is divided by 16 and then multiplied by the PLL. The VCO within

the PLL operates over a range of 200 to 400 MHz. Its output is scaled by a

divider that is configured by either the serial or parallel interfaces. The

crystal oscillator frequency f

post-divider N determine the output frequency.

, the PLL feedback-divider M and the PLL

XTAL

The feedback path of the PLL is internal. The PLL adjusts the VCO output frequency to be⋅M times the reference frequency by

adjusting the VCO control voltage. Note that for some values of M (either too high or too low) the PLL will not achieve phase lock.

The PLL will be stable if the VCO frequency is within the specified VCO frequency range (200 to 400 MHz). The M-value must be

programmed by the serial or parallel interface.

The PLL post-divider N is configured through either the serial or the parallel interfaces, and can provide one of four division

ratios (1, 2, 4, or 8). This divider extends performance of the part while providing a 50% duty cycle. The output driver is driven

differentially from the output divider, and is capable of driving a pair of transmission lines terminated 50Ω to V

– 2.0V. 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: serial and parallel. The parallel interface uses the values at the M[8:0] and N[1:0]

inputs to configure the internal counters. It is recommended on system reset to hold the P_LOAD input LOW until power becomes

valid. On the LOW–to–HIGH transition of P_LOAD, the parallel inputs are captured. The parallel interface has priority over the

serial interface. Internal pullup resistors are provided on the M[8:0] and N[1:0] inputs prevent the LVCMOS compatible control

inputs from floating.

The serial interface centers on a fourteen bit shift register. The shift register shifts once per rising edge of the S_CLOCK input.

The serial input S_DATA must meet setup and hold timing as specified in the AC Characteristics section of this document. The

configuration latches will capture the value of the shift register on the HIGH–to–LOW edge of the S_LOAD input. See the

programming section for more information. The TEST output reflects various internal node values, and is controlled by the T[2:0]

bits in the serial data stream. In order to minimize the PLL jitter, it is recommended to avoid active signal on the TEST output.
