1
SDA
I²C Serial Data.
2
SCL
I²C Serial Clock.
3
GND
Electrical and Case Ground.
4
CLK+
Clock Output.
5
CLK-
Complementary clock output (LVPECL, LVDS, HCSL, and
Complementary dual CMOS formats).
Clock output for in-phase dual CMOS format.
No connect (N/C) for single-ended CMOS format.
6
V_DD
Power Supply Voltage.
5.1. Dual CMOS (1:2 Fanout Buffer)
Dual CMOS output format ordering options support either complementary or in-phase output signals. This feature
enables replacement of multiple XOs with a single Si514 device.
