Name/Description

115

PDDMXN

Iu

CMOS Powerdown Demultiplexer Circuit (Active-Low).

0 = demultiplexer powered off, D[15:0]P/N and PARITYP/N

are high-impedance

1 or no connection = demultiplexer powered on

117

MUTEDMXN

Iu

CMOS Mute Data to Demultiplexer Circuit (Active-Low).

0 = mute data

1 or no connection = normal data

108

CK155P

107

CK155N

O LVPECL Recovered Clock Output (155 MHz).

155 MHz recovered differential clock output. Pins are active

but forced to differential logic low when MUTE155N = 0.

114

MUTE155N

Iu

CMOS Mute CK155P/N Clock Output (Active-Low). Forces

CK155P/N to logic low when MUTE155N is active.

0 = muted

1 or no connection = enabled

105

PARITYP

104

PARITYN

O LVPECL Parity Input Over Data (D[15:0]). Active only when

PDDMXN = 1.

111

REFCLKP

110

REFCLKN

I

LVPECL Reference Clock Input (155 MHz). This clock is optional. If

applying the REFCLKP/N, set the REFCLKP/N to one of

the following frequencies:

s 155.52 MHz if using the TRCV012G5, or the

TRCV012G7 at the 0C-48/STM-16 rate of 2.48832 GHz.

113

REFSELN

s 166.62 MHz if using the TRCV012G7 at the RS FEC

0C-48/STM-16 rate of 2.66606 GHz.

Iu

CMOS Reference Select to PLL. Selects LAINP/N or DATAP/N, or

REFCLKP/N as the input to the CDR PLL.

0 = select REFCLKP/N

1 or no connection = select LAINP/N or DATAP/N

* 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. Iu = an internal pull-up resistor on this pin, Id = an internal pull-down resistor on this pin, It = an internal termination resis-

tance of 50 Ω on this pin.
