Pin Description
Pin Number
Pin Name
Pin Function
1
VEE
Ground.
2
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 XTAL input. If LOW, it selects CLK 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
CLK
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, 7
XTAL_IN,
XTAL_OUT
Crystal oscillator interface. XTAL_IN is the input. XTAL_OUT is the output.
5, 8, 9
NC
Unused Pins
10, 13, 18
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. See “Truth Table” below.
