Integrated T1/E1/J1 Short-Haul and

Long-Haul Protection Switch

General Description

Features

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.

ꢀ Single +3.3V Supply Voltage

ꢀ Quad-DPDT/Octal-SPDT Switches Support

Two T1/E1/J1 Ports

ꢀ Low R_ON

ꢀ 0.7Ω (typ) in Transmit Path; 5Ω (typ) in

Receive Path

ꢀ Low C_ON/C_OFF

60pF/40pF (typ) in Transmit Path

24pF/12pF (typ) in Receive Path

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).

ꢀ Chip Surge Protection

IEC 61000-4-5 (8µs to 20µs Surge)

Class 2 ( 1ꢀV)

ꢀ -70dB (typ) Crosstalꢀ/Off-Isolation (3MHz)

ꢀ Small, 32-Pin TQFN Pacꢀage

The MAX4670 has four 1.0Ω (max) on-resistance switch-

es with 60pF/40pF on-/off-capacitances for interfacing to

the LIU transmitter outputs. The MAX4670 also includes

four 10Ω (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.
