Symbol
*
* Differential pins are indicated by the P and N suffixes. For nondifferential pins, N at the end of the symbol name designates active-low.
I = input, O = output. I
u
= an internal pull-up resistor on this pin, I
d
= an internal pull-down resistor on this pin, I
t
= an internal termination

Name/Description
B1
MUTEDMXN
CMOS
Mute DeMUX Parallel Output Data (Active-Low).
Forces all
demultiplexer output data D[15:0] to a logic-low level.
0 = Demultiplexer output muted.
1 or no connection = Normal operation.
Mute CK622P/N Clock Output (Active-Low).
Forces
CK622P/N to logic low when MUTE622N is active.
0 = Muted.
1 or no connection = Enabled.
CKO Frequency Select.
Selects 155 MHz or 622 MHz clock
frequency on CLKOP/N.
0 = 155 MHz CKOP/N.
1 or no connection = 622 MHz CKOP/N.
Mute CKOP/N Clock Output (Active-Low).
Forces CKOP/N
to logic low when MUTECKON is active.
0 = Muted.
1 or no connection = Enabled.
Reference Frequency Select.
Sets clock and data recovery
(CDR) PLL to accept 155 MHz, or 622 MHz reference
frequency on REFCLKP/N.
0 = 155 MHz REFCLKP/N.
1 or no connection = 622 MHz REFCLKP/N.
Reference Clock Input (155 MHz, or 622 MHz).
