Pin Configuration
16-Pin QFN
Pin Description
Pin Number
Pin Name
Pin Function
12, 9
IN, /IN
Differential input. Internal 50 termination resistors to VT input. Flexible input accepts any
differential input. See the Input Interface Applications section.
1, 2, 3, 4
Q0, /Q0
Q1, /Q1
Differential buffered LVPECL Outputs. Divided by 1, 2, 4, 8, or 16. See Truth Table. Unused
PECL outputs may be left floating with no impact on jitter performance.
16, 15, 5
S0, S1, S2
Select pins. See Truth Table. LVTTL/CMOS logic levels. Internal 25k pull-up resistor. Logic
HIGH if left unconnected (divided by 16 mode). Input threshold is VCC/2.
6
NC
No connect.
8
/RESET
/DISABLE
LVTTL/CMOS logic levels. Internal 25k pull-up resistor. Logic HIGH if left unconnected. Apply
LOW to reset the divider (divided by 2, 4, 8, or 16 mode). Also acts as a synchronous
disable/enable function. The reset and disable function occurs on the next HIGH-to-LOW clock
input transition. Input threshold is VCC/2.
10
VREF-AC
Reference voltage. Equal to VCC-1.4V (approximately). Used for AC-coupled applications only.
Decouple the VREF-AC pin with a 0.01F capacitor. See the Input Interface Applications section.
11
VT
Termination center tap. For CML or LVDS inputs, leave this floating. Otherwise, see Figures 2a to
2f within the Input Interface Applications section.
7, 14
VCC
Positive power supply. Bypass with .01F /0.01F low-ESR capacitor.
13
GND
Ground.
