Line Card Access Switch

VE750 Series

DESCRIPTION

The VoiceEdge™ family VE750 series of Line Card Access

Switches (LCAS), which includes the Le75181, Le75282 and

Le75183 devices, is a family of monolithic solid-state switches

that is designed to provide both power ringing access and test

access on the analog line card. These devices, while not a pin-

for-pin replacement for the traditional electromechanical relay

(EMR) solution, provide the equivalent switching functionality.

The VE750 series of LCAS is meant as a solid-state alternative

to the EMRs.

The Le75183A/B/C/D devices are pin-for-pin compatible with

Legerity’s L7583A/B/C/D devices.

Legerity also offers a range of compatible SLIC devices and

codec/filters that can be used with the VE750 series LCAS for

complete line card solutions that can be used worldwide in

analog line card applications.

PRODUCT DESCRIPTION

Data Sheet

The Le75183A/B/C/D Line Card Access Switch is a monolithic solid-state device providing the equivalent switching functionality

of three 2 form C switches. The Le75183 is designed to provide power ringing access, line test access (test out), and SLIC test

access (test in) to tip and ring in central office, digital loop carrier, private branch exchange, digitally added main line, and hybrid

fiber coax/fiber-in-the-loop analog line card applications. An additional pair of solid-state contacts are also available to provide

access for testing of the ringing generator.

The Le75183A/B has seven states: the idle talk state (line break switches closed, all other switches open), the power ringing state

(ringing access switches closed, all other switches open), loop access (test out) state (loop access (test out) switches closed, all

other switches open), SLIC test state (test in switches closed, all other switches open), simultaneous loop and SLIC access state

(loop and test in switches closed, all others open), ringing generator test state (ring test switches closed, all others open), and

an all OFF state. The seven states in the Le75183A/B are also in the Le75183C/D, with an additional simultaneous test-out and

ring-test state, making the Le75183C/D appropriate for digital loop carrier and other Telcordia TR-57 applications.

The Le75183 offers break-before-make or make-before-break switching, with simple logic level input control. Because of the

solid-state construction, voltage transients generated when switching into an inductive ringing lead during ring cadence or ring

trip are minimized, possibly eliminating the need for external zero cross switching circuitry. State control is via logic level inputs,

so no additional driver circuitry is required.

The line break switch is a linear switch that has exceptionally low ON-resistance and an excellent ON-resistance matching

characteristic. The ringing access switch has a breakdown voltage rating >480 V which is sufficiently high, with proper protection,

to prevent breakdown in the presence of a transient fault condition (i.e., passing the transient on to the ringing generator).

Incorporated into the Le75183A and Le75183C is a diode bridge/SCR clamping circuit, current-limiting circuitry, and a thermal

shutdown mechanism to provide protection to the SLIC device and subsequent circuitry during fault conditions. This is shown in

block diagram as version A/C. Positive and negative lightning is reduced by the current-limiting circuitry and steered to ground

via diodes and the integrated SCR. Power cross is also reduced by the current-limiting and thermal shutdown circuits.

The Le75183B and Le75183D versions provide only an integrated diode bridge along with current limiting and thermal shutdown

(see block diagram for version B/D). This will cause positive faults to be directed to ground and negative faults to battery. In either

polarity, faults are reduced by the current-limit and/or thermal shutdown mechanisms.

To protect the Le75183 from an overvoltage fault condition, use of a secondary protector is required. The secondary protector

must limit the voltage seen at the tip/ring terminals to prevent the breakdown voltage of the switches from being exceeded. To

minimize stress on the solid-state contacts, use of a foldback- or crowbar- type secondary protector is recommended. With proper

choice of secondary protection, a line card using the Le75183 will meet all relevant ITU-T, LSSGR, FCC, or UL* protection

requirements.

The Le75183 operates off of a 5-V supply only. This gives the device extremely low idle and active power dissipation and allows

use with virtually any range of battery voltage. This makes the Le75183 especially appropriate for remote power applications

such as DAML or FOC/FITL or other Telcordia TA 909 applications where power dissipation is particularly critical.

A battery voltage is also used by the Le75183, only as a reference for the integrated protection circuit. The Le75183 will enter an

all OFF state upon loss of battery.

During power ringing, to turn on and maintain the ON state, the ring access switch and ring test switch will draw a nominal 2 mA

from the ring generator.

The default power up state of Le75183 is in all OFF state, unless otherwise being overwritten by external controls.

The Le75183 device is packaged in a 20-pin, plastic SOIC (GULL) (Le75183ASC/BSC/CSC/DSC), a 32-pin QFN (Le75183AQC/

BQC/CQC/DQC), and a 28-pin, plastic SOIC (GULL) (Le75183AESC/BESC/CESC/CZESC/DESC). The 28-pin package is

available to support existing designs. For new designs, it may be advantageous to use the other two packages for smaller in size.
