LVPECL Outputs—OUT0 to OUT5
The LVPECL differential voltage (VOD) is selectable from ~400 mV
to ~960 mV (see Register 0x0F0[3:2] to Register 0x0F5[3:2]).
The LVPECL outputs have dedicated pins for power supply
(VS_LVPECL), allowing a separate power supply to be used.
VS_LVPECL can be from 2.5 V to 3.3 V.
The LVPECL output polarity can be set as noninverting or
inverting, which allows for the adjustment of the relative
polarity of outputs within an application without requiring a
board layout change. Each LVPECL output can be powered
down or powered up, as needed. Because of the architecture of
the LVPECL output stages, there is the possibility of electrical
overstress and breakdown under certain power-down conditions.
For this reason, the LVPECL outputs have several power-down
modes. This includes a safe power-down mode that continues
to protect the output devices while powered down, although it
consumes somewhat more power than a total power-down. If
the LVPECL output pins are terminated, it is best to select the
safe power-down mode. If the pins are not connected (unused),
it is acceptable to use the total power-down mode.

LVDS/CMOS Outputs—OUT6 to OUT9
OUT6 to OUT9 can be configured as either an LVDS
differential output or as a pair of CMOS single-ended outputs.
The LVDS outputs allow for selectable output current from
~1.75 mA to ~7 mA.
The LVDS output polarity can be set as noninverting or
inverting, which allows for the adjustment of the relative
polarity of outputs within an application without requiring a
board layout change. Each LVDS output can be powered down
if not needed to save power.
OUT6 to OUT9 can also be CMOS outputs. Each LVDS output
can be configured to be two CMOS outputs. This provides for
up to eight CMOS outputs: OUT6A, OUT6B, OUT7A, OUT7B,
OUT8A, OUT8B, OUT9A, and OUT9B. When an output is
configured as CMOS, CMOS Output A is automatically turned on.
CMOS Output B can be turned on or off independently. The
relative polarity of the CMOS outputs can also be selected for any
combination of inverting and noninverting (see Table 57 for
Register 0x140[7:5], Register 0x141[7:5], Register 0x142[7:5],
and Register 0x143[7:5]).

Figure 60. LVDS Output Simplified Equivalent Circuit with
3.5 mA Typical Current Source
Each LVDS/CMOS output can be powered down as needed to
save power. The CMOS output power-down is controlled by the
same bit that controls the LVDS power-down for that output.
This power-down control affects both CMOS Output A and
CMOS Output B. However, when CMOS Output A is powered up,
CMOS Output B can be powered on or off separately.

RESET MODES
The AD9516 has several ways to force the chip into a reset
condition that restores all registers to their default values and
makes these settings active.
Power-On Reset—Start-Up Conditions When VS Is
Applied
A power-on reset (POR) is issued when the VS power supply is
turned on. This initializes the chip to the power-on conditions
that are determined by the default register settings. These are
indicated in the Default Value (Hex) column of Table 52. At
power-on, the AD9516 also executes a SYNC operation, which
brings the outputs into phase alignment according to the default
settings.
Asynchronous Reset via the RESET Pin
An asynchronous hard reset is executed by momentarily pulling
RESET low. A reset restores the chip registers to the default settings.
Soft Reset via Register 0x000[2]
A soft reset is executed by writing Register 0x000[2] and
Register 0x000[5] = 1b. This bit is not self-clearing; it must be
cleared by writing Register 0x000[2] and Register 0x000[5] = 0b to
reset it and complete the soft reset operation. A soft reset restores
the default values to the internal registers. The soft reset bit does
not require an update registers command (Register 0x232) to be
issued.
