Product Preview
Power Line Communication
Modem
The NCN49599 is a powerful spread frequency shift keying
(S−FSK) communication system−on−chip (SoC) designed for
communication in hostile environments.
It combines a low power ARM Cortex M0 processor with a high
precision analogue front end and a robust line driver. Based on 4800
baud S−FSK dual−channel technology, it offers an ideal compromise
between speed and robustness.
It is functionally compatible with the NCN49597 and NCS5651
chip set, offering frequencies to cover all CENELEC bands for use in
applications such as e−metering, home automation and street lighting.
The NCN49599 benefits for more than 10 years of field experience in
e−metering and delivers innovative features such as a smart
synchronization and in−band statistics.
Fully reprogrammable, the modem firmware can be updated in the
field. Multiple royalty−free firmware options are available from
ON Semiconductor; refer to the separate datasheets for details. The
configurable GPIOs allow connecting peripherals such as LCDs or
metering ICs.

Figure 1. Typical Application for the NCN49599 S−FSK Modem
Figure 1 shows an S−FSK PLC modem built around the
NCN49599. The design is a good starting point for a
CENELEC. EN 50065−1−compliant system; for further
information refer to the design manual in [1].
This design is not galvanically isolated; safety must be
considered when interfacing to a microcontroller or a PC.
For synchronization the mains is coupled in via a 1 MW
resistor; the Schottky diode pair D
5
clamps the voltage
within the input range of the zero crossing detector.
In the receive path a 2
nd
order high pass filter blocks the
mains frequency. The corner point − defined by C
7
, C
8
, R
10
and R
11
− is designed at 10 kHz. In the transmit path a 3
rd
order low pass filter built around the internal power
operational amplifier suppresses the 2
nd
and 3
rd
harmonics
to be in line with the CENELEC EN50065−1 specification.
The filter components are tuned for a space and mark
frequency of 63.3 and 74 kHz respectively, typically for
e−metering in the CENELEC A−band. The output of the
amplifier is coupled via a DC blocking capacitor C
10
to a 2:1
transformer Tr1. The high voltage capacitor C
11
couples the
secondary of this transformer to the mains. High−energetic
transients from the mains are clamped by the protection
diode combination D

, together with D

Stresses exceeding those listed in the Maximum Ratings table may damage the device. If any of these limits are exceeded, device functionality
should not be assumed, damage may occur and reliability may be affected.
1. The upper maximum voltage rating on the clock pins XIN and XOUT is specified with respect to the output voltage of the internal core voltage
regulator. The tolerance of this voltage regulator must be taken into account. In case an external clock is used, care must be taken not to
damage the XIN pin.
2. The direction (input or output) of configurable pins (IO0...IO9) depends on the firmware.
Normal Operating Conditions
Operating ranges define the limits for functional
operation and parametric characteristics of the device as
described in the Electrical Characteristics section and for the
reliability specifications.

3. The direction and function of the general−purpose I/O’s is controlled by the firmware. Depending on the firmware behavior, a general− purpose
IO (GPIO) used as an output may appear as an open−drain, push−pull or open−source pin. Refer to the firmware documentation for details.
4. During boot (i.e., before firmware has been uploaded) this pin is an output and indicates the status of the boot loader. Once firmware has
been loaded, the pin is available as a GPIO.
5. During normal operation, this pin must be tied to ground (recommended) or left open.
6. If the modem is not loading the firmware from an external SPI memory, it is recommended that this pin is tied to ground or Vdd.
7. During normal operation, it is recommended that this pin is tied to ground.
8. During normal operation, this pin must be tied to Vdd.
9. If a general purpose IO is configured as an output, the pull−down resistor is disconnected.
