Register Descriptions
QAM Mapping Off
When this bit is 1, the L64777 stops QAM mapping.
When this bit is 0, the L64777 uses DVB-compliant
mapping. The reset value is 0.
PLL Oscillator Amplitude
This controls the amplitude of the on-chip PLL oscillator.
When this bit is 0, the L64777 is in low-power mode with
higher jitter. When this bit is 1, the L64777 is in
high-power mode with lower jitter. For normal operation,
set this bit to 0.
Reserved
This bit is reserved.
Reserved
This bit is reserved.
Initial OCLK Value
This is a 15-bit initial value for the OCLK PLL feedback
division. The reset value for bit 3 is 1; for all other bits it
is 0.
Reserved
This bit is reserved.
Initial ICLK Value
This is a 15-bit initial value for the ICLK PLL reference
division. The reset value for bit 1 is 1; for all other bits it
is 0.
