Example 8–1. Generating Three Output Clocks Using an ALTPLL Megafunction
LVDS data rate = 1 Gbps; serialization factor = 10; input reference clock = 100 MHz
The following settings are used when generating the three output clocks using an ALTPLL megafunction.
The serial clock must be 1000 MHz and the parallel clock must be 100 MHz (serial clock divided by the
serialization factor):

Frequency = 1000 MHz (multiplication factor = 10 and division factor = 1)
Phase shift = –180° with respect to the voltage-controlled oscillator (VCO) clock
Duty cycle = 50%
Frequency = (1000/10) = 100 MHz (multiplication factor = 1 and division factor = 1)
Phase shift = (10 - 2) × 360/10 = 288° [(deserialization factor - 2)/deserialization factor] × 360°
Duty cycle = (100/10) = 10% (100 divided by the serialization factor)
Frequency = (1000/10) = 100 MHz (multiplication factor = 1 and division factor = 1)
Phase shift = (–180/10) = –18° (c0 phase shift divided by the serialization factor)
Duty cycle = 50%
