chipset must be used without substituting other manu-
facturer's parts on a chip-by-chip basis.
The termination networks in the MXL1344A can be set
to one of three modes, V.11, V.35, or high impedance
(high-Z). As shown in Figure 4, in V.11 mode, switch S1

is closed and switch S2 is open, presenting 104Ω
across terminals A and B. In V.35 mode, switches S1
and S2 are both closed, presenting a T-network with
104Ω differential impedance and 153Ω common-mode
impedance. In high-Z mode, switches S1 and S2 are
both open, presenting a high impedance across termi-
nals A and B suitable for V.28 and V.10 modes.
