CPC5604
Introduction
The LITELINKTM (CPC5604) is a single package
International Data Access Arrangement solution that is
designed to be used in a variety of telephone applications including high performance 56kbps (V.90)
modems. The LITELINKTM uses advanced optical signal
coupling techniques to provide the required electrical
isolation between the telephone and the Customer
Premises Equipment (CPE). The LITELINKTM differs
from other solutions using optical or capacitive isolation
techniques by including the barrier inside the IC package, thus eliminating the need for external optocouplers
or high-voltage capacitors in the data path resulting in
overall reduced board space. The LITELINKTM has
been designed to meet or exceed the requirements of
international regulatory agencies.
For international PTT compliance external passive components can be changed to meet different country
requirements.
For added flexibility, a second device, the CPC5601,
can be used in conjunction with the CPC5604 to offer a
host programmable solution. The CPC5601 is programmed serially through the host’s microcontroller.
Using the CPC5601 along with the CPC5604 eliminates
the need to change external passive components allowing for a flexible, fully international DAA.
Ring Detection via Snoop Circuit
While in the on-hook state (OH deasserted), an internal
multiplexer turns on a “snoop” circuit that actively monitors the phone line for two conditions: incoming ring signal and Caller ID (CID) information. The snoop circuit
“snoops” the line continuously while drawing a low 2uA
max. current from the telephone line thus meeting regulatory requirements. When the central office (CO) places
a ring signal on the telephone line, 90VRMS max, the
RING output is pulsed from High to Low for 2 seconds at
the same frequency as the AC signal, typically 20Hz, and
restored to High during the 4 second delay. The ring
detection circuitry is designed to reject false signaling
from pulse dialing circuits or noise on the line.
the host asserts the CID line which automatically couples the snoop circuit to the RX outputs on the
LITELINKTM. After the CID signal is processed by the
host, the host will deactivate the CID signal. At this point
the host can answer the call by asserting the OH signal.
Note that when the LITELINKTM goes off-hook it automatically disconnects the snoop path from both RX and
RING outputs. Signals appearing on the telephone line
are now coupled through the optical isolation barrier in
the LITELINKTM and not via the snoop path.
Hook Switch Control
The OH or off-hook input is used to place the DAA on or
off-hook. When the input is High, the DAA is on-hook or
ready to receive calls from the CO. In this mode the
snoop circuitry is enabled as described above. Driving
OH Low places the DAA off-hook allowing the CO supplied loop current to flow (120mA max.), indicating the
DAA is answering or preparing to place a call.
Transmit Signal
Outgoing analog signals to be transmitted to the telephone lines are placed differentially on the TX+ and TXinputs of the CPC5604. Transmit level from the user
device is limited to 0dBm or 2.1Vp-p. The differential
transmit signal is converted to a single ended signal by
the CPC5604. The transmit signal is transferred across
an optical barrier by an electrical-optical-electrical
amplifier, which is transparent to the user. Variations in
gain due to electrical-optical-electrical efficiency are virtually eliminated by an on-chip automatic gain control
circuit which sets the input to output gain of the photodiode amplifier to 1. This results in a TX insertion loss of
+/- 1dB.
Caller ID (CID) Detection
via Snoop Circuit
CID is a service offered by the telephone company to
provide caller information (i.e. the caller’s telephone
number) to the called party. The CID signal is present on
the telephone line after the first ring burst is sent from
the CO. After this first ring burst is detected by the host,

Receive Signal Path (Refer to Block Diagram)
Transmit Signal Path (Refer to Block Diagram)
Signals to and from the telephone line to the LiteLinkTM
appear on Tip and Ring connections. The receive signal
is extracted from the transmit signal via the 2-4 wire
hybrid block. The receive signal is then converted to
infrared light by the receive photodiode amplifier and LED
front end. The intensity of the infrared light is modulated
by the receive signal and this light is transferred across
the electrical isolation barrier via reflective dome to a photodiode where the light is converted to a photocurrent.
This photocurrent is a highly linear representation of the
receive signal and is amplified and converted to a voltage. This single ended voltage is converted to a differential voltage signal where it is presented as RX+ and RXand connects to the receive inputs of the host data pump.
Signals that are to be sent from the host to the telephone line are placed differentially on TX+ and TX-. The
maximum value of the transmit signal should not
exceed 0dBm or 2.18Vpp. The differential transmit signal is converted to a single ended signal by the
LiteLinkTM. This signal is coupled to the transmit photodiode amplifier in a similar manner to the receive path.
Variations in gain due to quantum efficiency of the optics
are virtually eliminated by an on chip AGC circuit which
automatically sets the input to output gain of the photoamplifier to unity. This means that the receive signal on
the telephone line is faithfully reproduced at the RX outputs in terms of amplitude to within 2dB of the received
signal. Distortion at the RX outputs is -80dB maximum at
a receive level of -3dB over the band of 30Hz-4kHz.
At the output of this amplifier the voltage signal is coupled to a voltage to current converter via a transconductance stage where the transmit signal modulates the
telephone line loop current. As in the receive stage, the
gain of the transmit photodiode amplifier is set to unity
automatically thereby limiting insertion loss to 0±1dB.
Figures 2C and 2D illustrate connection to the host differentially and single ended respectively.

Single supply operation requires that the RX outputs be

Ring Signal Detection
The snoop circuit actively monitors the telephone line
for 2 conditions:
1. Incoming ring signal
2. Caller ID information
Care should be taken when using this equation since
RRXF (R3), CS (C6 or C7), and RSNOOP (R5 or R6)
affect receive gain and Caller ID gain. It is recommended that RRXF (R3) be set to the typical value and
then after adjusting the ring detect threshold, check that
CID gain is acceptable.
Caller ID Detection
Figure 2D Connection To Host Single Ended

Caller ID (CID) is a service offered by the telephone
company to provide caller information (i.e. caller’s telephone number) to the called party. CID service is
optional and signals only appear on the telephone lines
of subscribers that pay for this feature. The CID information appears on the telephone line after the first ring
burst is sent from the central office (CO).

SINGLE ENDED CONNECTION TO CPC5604A
The Snoop circuit “snoops” the line continuously while
the LiteLinkTM is in the on-hook mode. Current taken
from the telephone line in the on-hook condition by the
LITELINKTM is maintained at a low 2uA maximum thus
meeting regulatory requirements for minimum on-hook
impedance limitation. When the central office places
the ring signal on the telephone line, that signal is coupled through a pair of RC circuits to a differential amplifier in the LiteLinkTM.
Referring to Block Diagram, snoop capacitors connected to the SNP1/SNP2 pins provide a high voltage isolation barrier between the host and the telephone line
while coupling the AC signals to the snoop amplifier.
The ring signal is digitized and brought out to the RING
pin where the host can qualify it as a valid ring signal.
The ring detection threshold is dependent on the values
of 3 external components: RRXF (R3), RSNOOP (R5 or
R6), and CS (C6 or C7). The default values in the typical bill of materials reflects the parameters in the data
sheet for typical operation. If it is desired to change the
threshold, the values can be selected by using the
equation:

The LiteLinkTM is designed to meet various country DC
characteristics including the CTR-21 standard. The pins
that control the VI characteristics and current limiting are
designated ZDC and DCS. Meeting DC requirements
are achieved by selecting the appropriate resistors RZDC
(R16) and RDCS (R20) respectively. Resistor values can
also be switched in and out with the CPC5601device or
optocouplers which enables international compliance
under software control. Suggested resistor values for
various countries are listed in table 1. The VI profile on
Tip and Ring is described by the following equation:
CID
VLINE = VBRIDGE +
This CID signal is then processed by the host and, after
processing, the host will deactivate the CID signal. At
this point the host can answer the call if desired by
asserting the OH pin on the LiteLinkTM. It’s important to
note that when the LiteLinkTM goes off-hook, it automatically disconnects the snoop path from both the RX
and Ring outputs. Signals appearing on the telephone
line are now coupled through the optical isolation barrier in the LiteLinkTM and not via the capacitors in the
snoop path.

On-Hook Resistance
CTR-21 Compliance
Figure 4 shows the test setup for on-hook DC resistance. The battery is set to 100VDC and an ammeter is
placed in series with the battery connection. When the
DAA is in the on-hook state, the leakage current is
obtained and then the battery voltage is divided by this
current yielding the on-hook resistance. The LiteLinkTM
is guaranteed to have a leakage current < 10uA at 100V
which is equivalent to an on-hook resistance > 10MΩ
thus meeting regulatory approvals.
CTR-21 is the standard for connection of data communications equipment to the European telephone network. The maximum current limit requirement in
CTR-21 (Section 4.7.1) is 60mA and can be selected by
the following equation:
Current Limiting
The LiteLinkTM includes a current limiting feature that is
selectable via resistor RZDC (R16). The current limit
value is set by the equation:
10
1V
1V
RZDC
+ 8mA
Clare recommends current limit be set to 53mA using an
RZDC value of 22Ω. Since VDD is regulated to +3.5V,
excess power is dissipated in the external MOSFET
package. Since the maximum off-hook line voltage and
current in CTR-21 is 40V and 53mA respectively, the
maximum power dissipated by the MOSFET is approximately 2.1W.
12
RZDC
AC Characteristics
For US/Canada/Japan the recommended value for
RZDC (R16) is 8Ω which yields a current limit value of
133mA. The current limiting feature is especially useful
in the case where the host system is inadvertently connected to a digital PBX telephone port which usually has
a very high current limit value. The current limiting capability will prevent damage to the LiteLinkTM in this scenario.
XXX
ILM =
In a similar manner to the DC characteristics, AC termination impedance is set via RZNT (R18). For all applications, a 604W resistor for RZNT (R18) is required to
reflect 600W to the CO.

CPC5604
Differential and Single Ended Mode
The LiteLinkTM is designed to support either differential
or single ended signals on Tx and/or Rx pins. The decision of which topology to use is based on the particular
chipset being used to drive the LiteLinkTM. For example,
most Lucent modem chips require both differential
receive and transmit ability, while most Rockwell
devices require differential transmit and single ended
receive. The LiteLinkTM supports a full 0dBm differential
signal on its Tx inputs.

a signal into the Tx inputs and measures the energy at
Rx with Tip and Ring terminated by a 600Ω nominal
impedance. The Tx input frequency is swept from 30Hz4000Hz and the amplitude of the signal is measured on
the Rx inputs and graphed in Figure 6B.

Return Loss
The return loss is a measure of impedance mismatch
between a terminating impedance (DAA) and a source
impedance (reference impedance). The AP measures
the return loss vs. frequency with the addition of the
bridge circuit show in Figure 7A. For this test, the refer-
ence impedance is set by the 600Ω nominal impedance, ZREF. The impedance that this is to be compared
to is across Tip and Ring connections. The AP sweeps
frequency and graphs frequency vs. return loss as
shown in Figure 7B.

Snoop Mode Frequency Response
Figure 8A can be used as a reference test setup for this
test with the difference being that the DAA is now in the
on-hook mode. In the on-hook mode, the snoop circuit
path is the signal path from Tip and Ring to Rx through
the capacitive barrier CS instead of the optical path.
Snoop frequency response graph is shown in Figure 8B.

Snoop Mode Distortion
Figure 9A can be used for the snoop mode distortion
test. Snoop mode operation requires that the DAA be in
—
the on-hook state and the CID pin asserted (driven
Low). Distortion in the snoop mode is not critical since
signals coupled through the snoop circuit are either
20Hz ring signals or FSK CID signals. A graph of
THD+N for the snoop mode is shown in Figure 9B.

Snoop Mode Common Mode Rejection Ratio (CMRR)
as possible and kept equidistant from one another.
Spacing of 0.1” should be maintained between traces
on the phone line side. If possible, traces should be
routed away from large 60Hz fields to prevent noise
inducement into the snoop circuit.
As a practical matter, CMRR is dependent on how well
the external snoop network CS and RSNOOP are
matched. It is recommended that capacitors CS (C6 or
C7) be ceramic NPO (COG) type for excellent temperature stability and have a tolerance of 5% or less.
Resistor tolerance for RSNOOP (R5 or R6) should also
be at least 5% or better.
Figure 10A shows the test setup for CMRR through the
snoop signal path. For this test the LITELINKTM is onhook and the frequency is swept from 20Hz to 4kHz.
Figure 10B is a graph of CMRR vs. frequency.
Careful consideration should be taken related to PCB
layout of the snoop network. Traces should be as short

Interconnection diagram is based on the Conexant(Rockwell) RC56D Chip solution.
1. Conexant Chipsets rely on a 6dB loss between MDP and tip and ring. This
is solved by placing the R1, R2, R3, resistor circuit in the Transmit Path
and the use of a single end of the differential receive.
