Device Operation

INPUT INTERFACING

Numerous input configurations exist for applying PECL,

LVPECL, and LVDS signals to the input of the CLC001.

Inputs may be single-ended or differential, AC or DC

coupled.

The V

BB pin may be used to provide a DC bias voltage to

the inputs. Leave this pin as a no connect when no bias is

needed. Note that DC-coupled inputs such as direct

LVDS and LVPECL connections are self-biasing and do

not require use of the V

BB pin. IBB, the current produced

by the V

BB pin, depends on RREF. For a given RREF, the

BB current will remain constant, and the bias voltage is

determined by the value of resistance, R

BB, between the

BB pin and ground. Figure 3 and Figure 4 show how RBB

corresponds to some common V

BB values with RREF held

at 1.91 k

Ω and 1.5 kΩ, respectively. Some common input

configurations are shown in

Figure 5 through Figure 9.
