1. Power solutions
1.2 Discretes
The power consumption of STBs and other consumer appliances is
progressively going down, because of new efficiency requirements
and new power conservation regulations. This trend, among other
factors, enables the usage of our new medium power Schottky diodes
in the AC/DC 12 V rail.
Our medium power Schottky diodes in SOD123W and SOD128
packages are used as freewheeling diodes on the secondary side,
with an operating range of 30 to 60 V and 1 to 5 A. Recommended
products include PMEG6030EP and PMEG4050EP.
• Our TL431xxFDT series offer enhanced EMI ruggedness, an
outstanding step response, and stability area for all SMPS
applications.
Our portfolio covers digital STBs for cable, satellite, and terrestrial
reception. We offer flexible platform development, whether the
system is being optimized for low cost or high performance. The
portfolio includes single and multiple tuners with optional loop-through
circuitry (but without external splitters), as well as the possibility
One product can be used for several designs, including cable and
terrestrial formats, and our software drivers simplify design work even
further. All our tuners deliver excellent performance and are suitable
for high-end analog/digital applications. Also, our products have been
validated against major standards worldwide.

Silicon RF switch and MOSFET BF1108 and BF1118
NXP’s silicon tuners offer built-in loop-through functionality in standby
mode. Depending on the power requirements of the intended system,
designers may choose to implement the loop-through function outside
the tuner, using an external part. In this case, the BF1108/BF1118 is
the recommended solution. It lets the TV connection operate, without
quality loss, even when the STB is turned off. It is a depletion-type FET
and a band-switching diode in a single SOT143B package. Low loss and
high isolation provide excellent RF switching functions. The MOSFET
gate can be isolated from ground with the diode, resulting in low
losses. Integrated diodes between gate and source and between gate
and drain protect against excessive input voltage surges. The BF1108
operates at 5 V while the BF1118 is for designs using 3.3 V supply.
Features
Specially designed for low-loss RF switching up to 1 GHz
Easy to design-in
Power ON: high isolation (switch is open)
Power OFF: low losses (switch is closed)

Smart-card reader ICs TDA8024, TDA8025, and TDA8034
These are complete, cost-efficient analog interfaces for asynchronous
smart cards. They provide all the supply, protection, and control
functions between a smart card and the microcontroller. The TDA8025
is for use in smart cards operating at 1.8 or 3 V, while the TDA8024 is for
cards operating at 3 or 5 V. The TDA8034 is the same as the TDA8024,
but without a DC/DC converter. All are available with demo kits.
Selection tree for TDA8024, TDA8025 and TDA8034
TDA8034
The TDA8024 and TDA8034 are both NDS and EMV 4.2 compliant, and
they both can supply a VCC of 5 V to the smart card. The system supply
voltage influences device selection. Use the TDA8034 when the system
supply voltage is 5 V ± 3%. This will ensure that the card VCC value is
a minimum of 4.75 V with a current load of 65 mA. In systems that can
only supply a voltage of 5 V ± 10%, the TDA8024 is a better choice,
because it can guarantee a proper value on VCC = 5 V.
The TDA8034 is available in a 24-pin HVQFN or, to meet low-cost
requirements, can be housed in a 16-pin SO package. The TDA8034 is
not pin-compatible with the TDA8024, which has 28 pins.

6. Data transfer interfaces: ESD protection
6.1 ESD protection for USB
For designs that use a USB interface – to connect permanent data
storage devices using flash memory, for example – we offer a range
of protection devices. In addition to the IP4282 and IP4234, listed
below, the PESD5V0X1BL, PRTR5V0U2D, PRTR5V0U2AX, PRTR5V0U4D,
PRTR5V0U2F can also be used. Other options for USB, such as
alternative packaging (including CSP), flow-through routing, different
capacitance ratings, and support for On-The-Go (OTG) are also
available.
ESD protection device IP4282 with pass-thru routing
Simply place this UTLP device on top of the signal lines to provide ESD
protection. No additional PCB space is consumed, and there’s no need
for special routing. The extremely short distance between the ESD
diodes and the signal lines ensures very fast reaction times.
ESD protection device IP4234 with pi-filter concept
This device delivers excellent clamping performance and extremely
high robustness against ESD pulses (15KV IEC 61000-4-2 contact).

7.1 Microcontrollers
8/16/32-bit microcontrollers
We offer highly-integrated and cost-effective products,
from the smallest 8-bit to the highest performing 32-bit ARM
microcontrollers.
The LPC111x family, based on Cortex-M0, is an excellent choice for
standby microcontroller tasks. It can be used for power management,
system and human interface monitoring (including remote control and
keypad), signaling, LEDs, and more. The family delivers the outstanding
performance of a 32-bit architecture, with best-in-class power
consumption, and the optimized code footprint enables memory cost
reduction.
The NXP approach lets designers work with a single ARM development
environment to cover all their processing needs, from ARM7 and ARM9
to Cortex-M. Our portfolio also includes an industry-leading selection
of enhanced 80C51.

7.2 I2C GPIO expanders
Our GPIO expanders make it easy to increase the number of I/O using
the I2C-bus. Add inputs for a keypad, a switch, signal monitoring, or fan
control, or add outputs for LED control, an ACPI power switch, a relay,
timers, or sensors.
Combat “feature creep” by increasing the number of I/O ports instead
of adding a new microcontroller. Or, enable seamless migration to
a newer microcontroller and still keep the same peripherals. Using
expanders eliminates costly, congested PCBs, since a trace or wire isn’t
needed for each signal.
NXP offers an extremely wide selection. We have 4-, 8-, 16-, and 40-bit
formats, support quasi-directional and push-pull outputs, and offer
options with interrupts and/or resets — all in a wide range of packages.
These devices can be used in power supplies, STBs, and home
gateways, to determine the temperature or define the window for an
action, such as an interrupt, an alarm, fan control, or shutdown. We
offer a large selection of commonly used sensors, in a wide array of
package types.

7.4 I2C level shifters
These devices provide digital logic level translation between a host
processor and a slave device. This is an important part of voltage level
shifting, since the host processor’s I2C voltage continues to go down
while the voltages used by the peripheral devices remain unchanged.
We offer a very large selection of active and passive level shifters, and
have evolved our NVT20xx family to include widths of 1, 2, 3, 4, 6, 8,
and 10 bits.

Discrete components for the main processing board
8.1 Power solutions
Since integrated circuits typically use a lower core supply voltage
than interfaces and memory devices, most boards require a number
of different supply voltages. Our power solutions include a variety of
devices, including medium-power Schottky diodes, bipolar transistors,
and MOSFETs, to help create efficient, cost-effective linear regulators
and DC/DC converters.
The PBSS4041PZ can be used as a linear PNP regulator to generate
2.5 and 1.5 V analog supplies. It delivers excellent gain up to 15 A
ICM while supporting 5.7 A of continuous current.
Supporting 1.2 or 1.8 V or the LNB supply, the PMEG2005EH,
PMEG4010EH, and PMEG4030ER are excellent options for the
freewheeling Schottky diodes commonly used in DC/DC conversion.
The BSP030, a 10 A, N-channel MOSFET in an SOT233 package, can
be used as an external MOSFET for synchronous rectification.
The TL431xxSDT series of shunt regulators, along with the BC847, a
general-purpose transistor, are recommended for low-power, discrete
linear voltage regulators.
To complement function-specific solutions, such as modem, USB, and
audio interface devices, we offer general-purpose discrete devices that
are well suited for use on the main processing board.
The high-voltage switching diode BAS101S is recommended for use
as a bridge rectifier on the Tip and Ring wires. In this configuration,
it can be used for current steering, to maintain DAA operation, or for
connection to AC-coupled Tip and Ring ports.
For Tip and Ring control, as well as off-hook functionality, the high-
voltage transistors MMBTA42 or PBHV8540T are recommended.
For audio muting, there is the low-noise low VCEsat (BISS) transistor
PBSS2515E, which is housed in an ultra-small SOT416 package, and
the PBSS4140T, housed in the cost-efficient, high-volume SOT23
package.
Discrete PESD5V0xx protection diodes are also available for USB,
memory, audio, video, and HDMI interfaces. Please refer to the specific
chapters in this guide for details.
