MC14LC5447
Calling Line Identification (CLID)
Receiver with Ring Detector
The MC14LC5447 is a silicon gate HCMOS IC designed to demodulate Bell
202 and V.23 1200–baud FSK asynchronous data. The primary application for
this device is in products that will be used to receive and display the calling
number, or message waiting indicator sent to subscribers from participating
central office facilities of the public switched network. The device also contains
a carrier detect circuit and ring detector which may be used to power up the
device.
Applications for this device include adjunct boxes, answering machines,
feature phones, fax machines, and computer interface products.
The MC14LC5447 offers the following performance features.
• Ring Detector On–Chip
• Ring Detect Output for MCU Interrupt
• Power–Down Mode, Less than 1 µA
• Single Supply: + 3.5 to + 6.0 V
• Pin Selectable Clock Frequencies: 3.68 MHz, 3.58 MHz, or 455 kHz
• Two Stage Power–Up for Power Management Control
• Demodulates Bell 202 and V.23

DOR
Data Out Raw (Pin 14)
This pin presents the output of the demodulator whenever
CDO is low. This data stream includes the alternate 1 and 0
pattern, and the 150 ms of marking, which precedes the
data. At all other times, DOR is held high.
DOC
Data Out Cooked (Pin 15)
This output presents the output of the demodulator when-
ever CDO is low, and when an internal validation sequence
has been successfully passed. The output does not include
the alternate 1 and 0 pattern. At all other times, DOC is held
high.
VDD
Positive Power Supply (Pin 16)
The digital supply pin, which is connected to the positive
side of the power supply.
APPLICATIONS INFORMATION
The MC14LC5447 has been designed to be one of the
main functional blocks in products targeted for the CLASS
(Custom Local Area Signaling Service) market. CLASS is a
set of subscriber features now being presented to the con-
sumer by the RBOCs (Regional Bell Operating Companies)
and independent TELCOs. Among CLASS features, such as
distinctive ringing and selective call forwarding, the subscrib-
er will also have available a service known as Calling Num-
ber Delivery (CND) and message waiting. With these
services, a subscriber will have the ability to display at a mini-
mum, a message containing the phone number of the calling
party, the date, and the time. A message containing only this
information is known as a single format message, as shown
in Figure 9. An extended message, known as multiple format
message, can contain additional information as shown in
Figure 10.
The interface should be arranged to allow simplex data
transmission from the terminating central office, to the CPE
(Customer Premises Equipment), only when the CPE is in an
on–hook state. The data will be transmitted in the silent peri-
od between the first and second power ring after a voice path
has been established.
The data signaling interface should conform to Bell 202,
which is described as follows:
• Analog, phase coherent, frequency shift keying
• Logical 1 (Mark) = 1200 ± 12 Hz
• Logical 0 (Space) = 2200 ± 22 Hz
• Transmission rate = 1200 bps
• Application of data = serial, binary, asynchronous
The transmission level from the terminating C.O. will be
– 13.5 dBm ± 1.0. The expected worst case attenuation
through the loop is expected to be – 20 dB. The receiver
therefore, should have a sensitivity of approximately
– 34.5 dBm to handle the worst case installations.

Title: “Voice Band Data Transmission Interface Generic
Requirements”
Figure 7 is a conceptual design of how the MC14LC5447
can be implemented into a product which will retrieve the in-
coming message and convert it to EIA–232 levels for trans-
mission to the serial port of a PC. With this message and
appropriate software, the PC can be used to look up the
name and any additional information associated with the call-
er that had been previously stored.
Figure 8 is a conceptual design of an adjunct unit in paral-
lel with an existing phone. This arrangement gives the sub-
scriber CND service without having to replace existing
equipment.
