Pin Functions

PIN I/O DESCRIPTION
NAME NO.
POWER
GND 3 Ground Device Ground.
VDD 6 Power 3.3-V Power Supply.
OUTPUT BLOCK
OUT0, OUT1 4, 5 Output 3.3-V LVCMOS Output Pair (Outputs can be individually set to same polarity, opposite polarity, or tri-state) in LMK61E0M. By default, OUT0 is enabled and OUT1 is disabled and set at high impedance on power-up.
DIGITAL CONTROL / INTERFACES
ADD 2 LVCMOS When left open, LSB of I2C slave address is set to 01. When tied to VDD, LSB of I2C slave address is set to 11. When tied to GND, LSB of I2C slave address is set to 00.
OE 1 LVCMOS Output Enable (internal pullup). In LMK61E0M, when set to low, output on OUT0 is disabled and set at high impedance.
SCL 8 LVCMOS I2C Serial Clock (open-drain). Requires an external pullup resistor to VDD.
SDA 7 LVCMOS I2C Serial Data (bi-directional, open-drain). Requires an external pullup resistor to VDD.
