CLK_EN
Single-Ended Input: This TTL/CMOS input disables and enables the Q0-Q3 outputs. It is
internally connected to a 51k pull-up resistor and will default to a logic HIGH state if left open.
When disabled, Q goes LOW and /Q goes HIGH. CLK_EN being synchronous, outputs will be
enabled/disabled following a rising and a falling edge of the input clock. VTH = is approximately
1.5V.
3
CLK_SEL
Single-Ended Input: This single-ended TTL/CMOS-compatible input selects the input to the
multiplexer. If HIGH, selects CLK1 input. When LOW, it selects CLK0 input. Note that this input
is internally connected to a 51k pull-down resistor and will default to logic LOW state if left
open. VTH = is approximately 1.5V.
4
CLK0
Single-Ended Input: This LVCMOS or LVTTL signal is the input signal to the device. It is
internally connected to a 51k pull-down resistor and will default to a logic LOW state if left
open. This input is selected when CLK_SEL is set to logic LOW.
6
CLK1
Single-Ended Input: This LVCMOS or LVTTL signal is the input signal to the device. It is
internally connected to a 51k pull-down resistor and will default to a logic LOW state if left
open. This input is selected when CLK_SEL is set to logic HIGH.

VCC
Positive Power Supply Pins: Bypass with 0.1F||0.01F low ESR capacitors as close to the VCC
pins as possible.

LVPECL Differential Output Pairs: Differential buffered output copies the selected input signal.
The output swing is typically 800mV. Unused output pairs may be left floating with no impact on
jitter. These differential LVPECL outputs are a logic function of the CLK0 and CLK1 inputs. See
“Truth Table” below.
