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 refer to 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
1
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. MPC9773 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 MPC9773 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
