Pin Description (Continued)
Pin Number
Pin Name
Pin Function
7
LOS/SD
LVTTL Output. Signal detect (SD) asserts high when the data input amplitude rises above the
threshold sets by SDLVL. Conversely, loss-of-signal (LOS) deasserts low when the data input
amplitude rises above the threshold set by LOSLVL.
12, 9
DOUT, /DOUT
LVPECL Outputs. When JAM disables the device, output DOUT is forced to logic LOW and
output /DOUT is forced to logic HIGH.
13
LOS/SD SEL
Allows the user to select between whether LOS or SD is outputted on the LOS/SD pin. Also
controls the polarity of the JAM input. When SD is selected, JAM is active HIGH and LOS/SD
(Pin 7) operates as signal detect. Conversely, when LOS is selected, JAM is active LOW and
LOS/SD operates as loss-of-signal. This pin is internally connected to a 25k pull-up resistor
and defaults to HIGH (SD output selected).
14
LOS/SDLVL
Voltage Input. Sets the LOS/SD level. A resistor from this pin to VCC sets the threshold for the
data input amplitude at which LOS/SD will be asserted.
15
JAM
LVTTL Input. This JAM input acts as a squelch function and switches its polarity depending on
LOS/SD SEL status. When LOS is selected, this pin is active LOW. When SD is selected, this
pin is Active HIGH. To create a squelch function, connect JAM to LOS/SD. When JAM disables
the device, output Q is forced to logic LOW and output /Q is forced to logic HIGH. Note that this
input is internally connected to a 25k pull-up resistor.
