are internally pulled up to V
CC
to ensure
a logic HIGH if left unconnected.
No-Cable Mode
The MXL1543B will enter no-cable mode when the
mode-select pins are left unconnected or connected
high (M0 = M1 = M2 = 1). In this mode, the multiproto-
col drivers and receivers are disabled and the supply
current drops to 0.5μA. The receivers’ outputs enter a
high-impedance state in no-cable mode, which allow
these output lines to be shared with other receivers’
outputs (the receivers’ outputs have internal pullup
resistors to pull the outputs HIGH if not driven). Also, in
no-cable mode, the transmitter outputs enter a high-
impedance state so that these output lines can be
shared with other devices.
Dual Charge-Pump Voltage Converter
The MXL1543B’s internal power supply consists of a
regulated dual charge pump that provides positive and
negative output voltages from a +5V supply. The
charge pump operates in discontinuous mode. If the
output voltage is less than the regulated voltage, the
charge pump is enabled. If the output voltage exceeds
the regulated voltage, the charge pump is disabled.
Each charge pump requires a flying capacitor (C1, C2)
and a reservoir capacitor (C3, C5) to generate the V
DD
and V
EE
supplies. Figure 10 shows charge-pump con-
nections.
Fail-Safe Receivers
The MXL1543B guarantees a logic-high receiver output
when the receiver inputs are shorted or open, or when
they are connected to a terminated transmission line
with all the drivers disabled. This is done by setting the
receivers’ threshold between -25mV and -200mV in the
V.11 and V.35 modes. If the differential receiver input
