ABSOLUTE MAXIMUM RATINGS(1)
NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. Not to exceed 3.6V.

Type
Description
A[1:2]
I
Adjustable(1,4) Clock input. A[1:2] is the "true" side of the differential clock input.
A[1:2]
I
Adjustable(1,4) Complementary clock inputs. A[1:2] is the complementary side of A[1:2]. For LVTTL single-ended operation, A[1:2] should be set to the
desiredtogglevoltageforA[1:2]:
3.3V LVTTL VREF = 1650mV
2.5V LVTTL VREF = 1250mV
G1
I
LVTTL
Gate control for differential outputs Q1 and Q1 through Q5 and Q5. When G1is LOW, the differential outputs are active. When G1is
HIGH, the differential outputs are asynchronously driven to the level designated by GL(2).
G2
I
LVTTL
Gate control for differential outputs Q6 and Q6 through Q10 and Q10. When G2is LOW, the differential outputs are active. When G2is
HIGH, the differential outputs are asynchronously driven to the level designated by GL(2).
GL
I
LVTTL
Specifies output disable level. If HIGH, "true" outputs disable HIGH and "complementary" outputs disable LOW. If LOW, "true"
outputsdisableLOWand"complementary"outputsdisableHIGH.

I
LVTTL
Reference clock select. When LOW, selects A2 and A2. When HIGH, selects A1 and A1.
PD
I
LVTTL
Power-down control. Shuts off entire chip. If LOW, the device goes into low power mode. Inputs and outputs are disabled. Both
"true" and "complementary" outputs will pull to VDD. Set HIGH for normal operation.(3)
VDD
PWR
Power supply for the device core and inputs
GND
PWR
Power supply return for all power
N C
No connect; recommended to connect to GND
NOTES:
1. Inputs are capable of translating the following interface standards:
Single-ended 3.3V and 2.5V LVTTL levels
Differential HSTL and eHSTL levels
Differential LVEPECL (2.5V) and LVPECL (3.3V) levels
Differential LVDS levels
Differential CML levels
2. Because the gate controls are asynchronous, runt pulses are possible. It is the user's responsibility to either time the gate control signals to minimize the possibility of runt
pulses or be able to tolerate them in down stream circuitry.
3. It is recommended that the outputs be disabled before entering power-down mode. It is also recommended that the outputs remain disabled until the device completes power-
up after asserting PD.
4. The user must take precautions with any differential input interface standard being used in order to prevent instability when there is no input signal.
