Negative power supply
VCC_PLL
Supply
VCC
PLL positive power supply (analog power supply). It is recommended to use an external
RC filter for the analog power supply pin VCC_PLL. Please see applications section for
details.
VCC
Supply
VCC
Positive power supply for I/O and core. All VCC pins must be connected to the positive
power supply for correct operation

REF_SEL
1
Selects CCLKx as the PLL reference clock
Selects the LVPECL inputs as the PLL reference clock
CCLK_SEL
1
Selects CCLK0
Selects CCLK1
VCO_SEL

Selects VCO
÷2. The VCO frequency is scaled by a
factor of 2 (low VCO frequency range).
Selects VCO
÷1. (high VCO frequency range)
PLL_EN
1
Test mode with the PLL bypassed. The reference clock
is substituted for the internal VCO output. MPC97H73 is
fully static and no minimum frequency limit applies. All
PLL related AC characteristics are not applicable.
Normal operation mode with PLL enabled.
INV_CLK
1
QC2 and QC3 are in phase with QC0 and QC1
QC2 and QC3 are inverted (180
° phase shift) with
respect to QC0 and QC1
MR/OE
1
Outputs disabled (high-impedance state) and device is
reset. During reset/output disable the PLL feedback loop
is open and the internal VCO is tied to its lowest
frequency. The MPC97H73 requires reset after any loss
of PLL lock. Loss of PLL lock may occur when the
external feedback path is interrupted. The length of the
reset pulse should be greater than one reference clock
cycle (CCLKx). The device is reset by the internal
power–on reset (POR) circuitry during power–up.
Outputs enabled (active)
VCO_SEL, FSEL_A[0:1], FSEL_B[0:1], FSEL_C[0:1], FSEL_FB[0:2] control the operating PLL frequency range and input/output frequency
ratios. See Table 3 to Table 6 and the applications section for supported frequency ranges and output to input frequency ratios.
