MAX4815, MAX4816, MAX4817
High-Bandwidth, T1/E1, SPST Analog Switches
Relay Replacement for T1/E1 Redundancy Applications
|
Status
All versions are No Longer Available. See Ordering Information for recommended replacements.
Description
The MAX4815/MAX4816/MAX4817 high-bandwidth,
low-on-resistance, quad-SPST analog switches are
designed to serve as integrated T1/E1 protection
switches for 1+1 and N+1 line-card redundancy applications.
Each MAX4815/MAX4816/MAX4817 replaces four electromechanical relays, significantly reducing board space, simplifying PC board routing, and reducing
power consumption. These devices operate with ±3.3V or ±5V dual supplies for applications requiring T1/E1 signal switching in the line side of the interface transformer. Internal voltage multipliers drive the analog
switches, yielding excellent linearity and low 3.7Ω typical on-resistance within the T1/E1 analog signal range.
This high-bandwidth (550MHz typical) family of products
is optimized for low return loss and matched pulse
template performance in T1/E1 long-haul and short-haul
applications.
The MAX4815/MAX4816/MAX4817 are available in a
tiny 16-pin, 5mm x 5mm, thin QFN package and are
specified over the extended -40°C to +85°C temperature
range.
