[7:6]
Reserved
Reserved.
5
Mask Channel 1 sync
Masks the synchronous reset to the Channel 1 divider.
0 (default) = unmasked. The output drivers do not toggle until a SYNC pulse occurs.
1 = masked. Setting this bit asynchronously releases Channel 1 from the static sync state,
thus allowing the Channel 1 divider to toggle. Channel 1 ignores all sync events while this
bit is set. Setting this bit does not enable the output drivers connected to this channel.
In addition, the output distribution sync also depends on the setting of Register 0x0405[3].
4
Mask Channel 0 sync
Masks the synchronous reset to the Channel 0 divider.
0 (default) = unmasked. The output drivers do not toggle until a SYNC pulse occurs.
1 = masked. Setting this bit asynchronously releases Channel 0 from the static sync state,
thus allowing the Channel 0 divider to toggle. Channel 0 ignores all sync events while this
bit is set. Setting this bit does not enable the output drivers connected to this channel.
In addition, the output distribution sync also depends on the setting of Register 0x0405[3].
3
Reserved
Reserved.
2
Sync source selection
Selects the sync source for the clock distribution output channels.
0 (default) = direct. The sync pulse occurs on the next I/O update.
1 = active reference.
Note that the output distribution sync also depends on the APLL being calibrated and
locked, unless Register 0x0405[3] = 1b.
[1:0]
Automatic sync mode
Autosync mode.
00 = disabled. A sync command must be issued manually or by using the sync mask bits
in this register (Bits[5:4]).
01 = sync on DPLL frequency lock.
10 (default) = sync on DPLL phase lock.
11 = reserved.

Description
0x0501
7
Enable 3.3 V CMOS driver
0 (default) = disables 3.3 V CMOS driver, and OUT0 logic is controlled by Register 0x0501[6:4]
1 = enables 3.3 V CMOS driver as operating mode of OUT0.
This bit should be set to 1b only if Bits[6:4] are in CMOS mode.
[6:4]
OUT0 format
These bits set the OUT0 driver mode.
000 = PD, tristate.
001 (default) = HSTL.
010 = LVDS.
011 = reserved.
100 = CMOS, both outputs active.
101 = CMOS, P output active, N output power-down.
110 = CMOS, N output active, P output power-down.
111 = reserved.
[3:2]
OUT0 polarity
Controls the OUT0 polarity.
00 (default) = positive, negative.
01 = positive, positive.
10 = negative, positive.
11 = negative, nevative.
1
OUT0 drive strength
Controls the output drive capability of OUT0.
0 (default) = CMOS: low drive strength; LVDS: 3.5 mA nominal.
1 = CMOS: normal drive strength; LVDS: 4.5 mA nominal (LVDS boost mode).
Note that this is only in 3.3 V CMOS mode for CMOS strength. 1.8 V CMOS has only the
low drive strength.
0
Enable OUT0
Enables/disables (1b/0b) OUT0 1.8 V driver (default is disabled).
This bit does not enable/disable OUT0 if Bit 7 of this register is set to 1.
