Applications Information
Figure 2 shows a typical ISDN phone application of the
TP3076 together with a TP3420 ISDN Transceiver “S” Inter-
face Device and HPC16400 High-Performance Microcontrol-
ler with HDLC Controller. The TP3076 device is programmed
over
its
serial
control
interface
MICROWIRE/PLUS
serial I/O port.

POWER SUPPLIES
While the pins of the TP3076 COMBO II device are well pro-
tected against electrical misuse, it is recommended that the
standard CMOS practice of applying GND to the device be-
fore any other connections are made should always be fol-
lowed. In applications where the printed circuit card may be
plugged into a hot socket with power and clocks already
present, an extra long ground pin on the connector should be
used and a Schottky diode connected between V
BB
and
GND.
To minimize noise sources all ground connections to each
device should meet at a common point as close as possible
to the GND pin in order to prevent the interaction of ground
return currents flowing through a common bus impedance.
Power supply decoupling capacitors of 0.1 μF should be
connected from this common point to V
CC
and V
BB
as close
to the device pins as possible.
Further guidelines on PCB layout techniques are provided in
Application Note AN-614, “COMBO II
Programmable PCM
CODEC/Filter Family Application Guide”.
