Pin Information
(continued)
Note:
In Table 1, when operating the TRCV012G7 device at the OC-48/STM-16 rate, 2.5 Gbits/s should be inter-
preted as 2.48832 Gbits/s. When operating the TRCV012G7 device at the RS FEC OC-48/STM-16 rate,
2.5 Gbits/s should be interpreted as 2.66606 Gbits/s. (A similar interpretation should be made for 2.5 GHz.)

* 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
resistance of 50
on this pin.

I
Pins are high impedance when END2G5N = 1.
I
Pins are active but forced to differential logic low when
MUTE2G5N = 0.
Enable D2G5P/N Data Outputs (Active-Low).
0 = D2G5P/N buffer enabled
1 or no connection = D2G5P/N buffer powered off
Mute D2G5P/N Data Output (Active-Low).
0 = muted
1 or no connection = normal data
Recovered Clock Output (2.5 GHz).
2.5 GHz recovered differen-
tial clock output. Pins are high impedance when ENCK2G5N = 1.
Enable CK2G5P/N Clock Output (Active-Low).
0 = CK2G5P/N buffer enabled
1 or no connection = CK2G5P/N buffer powered off
Resistor Reference 1.
CML current bias reference resistor. (See
Table 16, page 22 for values.)
Resistor Reference 2.
CML bias reference resistor. Place a
1.5 k
resistor to V

Voltage Threshold Adjust Input.
This input is for monitoring
purposes only and should be left open (see Figure 3 on page 10).
Slice Level Adjustment.
Adjusts slice level for the limiting amp
(see Figure 3 on page 10).
Open Drain
Loss of Analog Signal (Active-Low).
Analog
Programming Voltage for LOSA Threshold.
Programming
voltage is scaled (see Figure 7 on page 16).
Open Drain
Loss of Digital Data (Active-Low).
CMOS
Input Loss of Signal (Active-Low).
Forces VCO to decrease to
its minimum frequency.
0 = force VCO low
1 or no connection = normal operation
Analog
Loop Filter PLL.
Connect LFP to VCP, and LFN to VCN.
