General Description
The MAX4670 is an integrated T1/E1/J1 analog protec-
tion switch for 1+1 and N+1 line-card redundancy
applications. It protects two T1/E1/J1 ports by combin-
ing eight SPDT switches in a single package. The
switch is optimized for high-return loss and pulse-tem-
plate performance in T1/E1/J1 long-haul and short-haul
applications. The part offers built-in chip-side surge
protection capability for short-haul intrabuilding appli-
cations.
The MAX4670 replaces two diode arrays or two tran-
sient voltage suppressors (TVSs) and four dual-SPDT
relays, significantly reducing board space and simplify-
ing PC board routing. The MAX4670 pinout is targeted
for T1/E1/J1 applications, resulting in a simplified layout
when interfacing with standard line transformers and
line interface units (LIUs).
The MAX4670 has four 1.0
(max) on-resistance switch-
es with 60pF/40pF on-/off-capacitances for interfacing to
the LIU transmitter outputs. The MAX4670 also includes
four 10
(max) on-resistance switches with low
24pF/12pF on-/off-capacitances for interfacing to the LIU
receiver inputs. Four logic inputs control the receive/
transmit pairs, in addition to a SWITCH input that con-
nects all switches to the system’s protection bus.
The MAX4670 operates from a single +2.7V to +3.6V
supply and is available in 32-pin thermally enhanced
TQFN package. The MAX4670 is specified over the
-40
°C to +85°C operating temperature range.
