Phase-Shifting the Output Clock
In full rate CMOS mode the data output bits normally
change at the same time as the falling edge of CLKOUT+,
so the rising edge of CLKOUT+ can be used to latch the
output data. In double data rate CMOS and LVDS modes
the data output bits normally change at the same time as
the falling and rising edges of CLKOUT+. To allow adequate
setup and hold time when latching the data, the CLKOUT+
signal may need to be phase-shifted relative to the data
output bits. Most FPGAs have this feature; this is generally
the best place to adjust the timing.
Figure 14. Phase-Shifting CLKOUT
The LTC2162/LTC2161/LTC2160 can also phase-shift the
CLKOUT+/CLKOUT–signalsbyseriallyprogrammingmode
control register A2. The output clock can be shifted by 0°,
45°, 90°, or 135°. To use the phase-shifting feature the
clock duty cycle stabilizer must be turned on. Another
control register bit can invert the polarity of CLKOUT+ and
CLKOUT–, independently of the phase-shift. The combina-
tion of these two features enables phase-shifts of 45° up
to 315° (Figure 14).
