T1/E1 Line Interface

the register. In either mode, a reset will set all reg-

isters to 0 and force the oscillator to its center

frequency before initiating calibration. A reset

will also set LOS high.

Power Supply

The device operates from a single +5 Volt supply.

Separate pins for transmit and receive supplies

provide internal isolation. These pins should be

connected externally near the device and decou-

pled to their respective grounds. TV+ must not

exceed RV+ by more than 0.3V.

Decoupling and filtering of the power supplies is

crucial for the proper operation of the analog cir-

cuits in both the transmit and receive paths. A 1.0

μF capacitor should be connected between TV+

and TGND, and a 0.1 μF capacitor should be con-

nected between RV+ and RGND. Use mylar or

ceramic capacitors and place them as closely as

possible to their respective power supply pins. A

68 μF tantalum capacitor should be added close

to the RV+/RGND supply. Wire-wrap bread-

boarding of the line interface is not recommended

because lead resistance and inductance serve to

defeat the function of the decoupling capacitors.
