DESCRIPTION…
The SP207H and SP211H are multi–channel RS-232 line transceivers configured to fit most
communication needs. The "H" series is based on Sipex's SP200 Series transceivers and has
been enhanced for speed. The data rate is improved to over 460kbps which easily meets the
230.4kbps data rates for V.34. The SP207H and SP211H use the same on-board charge pump
to provide ±10V voltage levels, using 0.1µF charge pump capacitors to save board space and
reduce circuit cost. The SP207HB, SP211H and SP211HB feature a low–power shutdown
mode, which reduces power supply drain to 1µA. A WakeUp function keeps the receivers active
in the shutdown mode (SP207HB and SP211HB only).

Figure 1. Charge Pump — Phase 1
negative side of capcitor C2. There is a free–
running oscillator that controls the four phases
of the voltage shifting. A description of each
phase follows.
Phase 1
— VSS charge storage —During this phase of the
clock cycle, the positive side of capacitors C1
and C2 are initially charged to +5V. Cl+ is then
switched to ground and the charge in C1– is
transferred to C2–. Since C2+ is connected to
+5V, the voltage potential across capacitor C2 is
now 10V.
Phase 2
— V transfer — Phase two of the clock con-
SS
nects the negative terminal of C2 to the VSS
storage capacitor and the positive terminal of C2
to ground, and transfers the generated –l0V to
C . Simultaneously, the positive side of capaci-
3
tor C 1 is switched to +5V and the negative side
is connected to ground.
Phase 3
— VDD charge storage — The third phase of the
clock is identical to the first phase — the charge
transferred in C produces –5V in the negative
1
terminal of C1, which is applied to the negative
side of capacitor C2. Since C2+ is at +5V, the
VCC = +5V
voltage potential across C2 is l0V.
Phase 4
— VDD transfer — The fourth phase of the clock
connects the negative terminal of C2 to ground,
and transfers the generated l0V across C2 to C4,
the VDD storage capacitor. Again, simultaneously
with this, the positive side of capacitor C1 is
switched to +5V and the negative side is con-
nected to ground, and the cycle begins again.
Since both V+ and V– are separately generated
from V ; in a no–load condition V+ and V– will
CC
be symmetrical. Older charge pump approaches
that generate V– from V+ will show a decrease in
the magnitude of V– compared to V+ due to the
inherent inefficiencies in the design.
The clock rate for the charge pump typically
operates at 15kHz. The external capacitors can
be as low as 0.1µF with a 16V breakdown
voltage rating.
Transmitter/Driver
The drivers are inverting transmitters which have
been improved for speed over the SP200 Series.
The transmitters accept either TTL or CMOS
inputs and output the RS-232 signals at data rates
over 400kbps. Typically, the RS-232 output volt
