is <V
Differential Input Reference Clock
EN_[A:B] is the enable pin. A LVCMOS high provides normal operation. A LVC-
MOS low selects a low power down mode.
Supply Ground
External 475Ω resistor connection to set the differential output current
Differential Reference Clock Output
Signal Detect, output for channels A and B. Provides a LVCMOS high output when
a valid input signal is detected. When low, SD_X indicates that the input signal
level is below the signal detect threshold level.
