Fiber Optic Receiver for 50 MBaud MOST
AFBR-2013 Receiver are designed to receive up to 25MBit/s optical data
which are biphase coded (up to 50Mbaud). They are packaged in 4-pin
transfer molded, low-cost packages ready for assembly into MOST®
plastic fiber optic connector receptacles. Output data has TTL switching
levels, compatible with MOST® Network Interface Controller ICs. These
optical components are specified for operation over a -40°C to +95°C
temperature range, and reliability requirements of automotive applications.
It is allowed to process the AFBR-2013 devices with reflow soldering. In
the absence of data activity, the receiver switches to very low power mode.

2G/3G/4G Multiband LTE Transceiver Chip
Fujitsu Semiconductor Wireless Products, Inc. (FSWP) today announced
that its second LTE multimode product, the MB86L11 2G/3G/4G transceiver,
is shipping in commercial quantities. The MB86L11 is a single chip
multiband, multimode transceiver that supports all wireless communication
modes including LTE (FDD & TDD), HSPA+, DC-HSPA, WCDMA, GSM,
EDGE, CDMA and TD-SCDMA. The MB86L11 transceiver incorporates
many advanced features, including envelope tracking (ET) and antenna
tuning (AT). For more information, please click here.
14.2W/in3 Power Density in T8 LED Driver
Power Integrations announced two new reference designs describing
high-efficiency, non-isolated, high-power-factor (PF) LED drivers for T8
tubes. The designs feature low component count and leverage simple
magnetics and single-sided boards yielding industry-leading power
densities of 14.2 W/in³. Based on the LNK460KG LED driver from Power
Integrations’ LinkSwitch-PL family of ICs, the circuits detailed in DER-
337 (high-line) and DER-345 (low-line) use single-stage non-isolated
topologies which result in a profile of only 8 mm – small enough to be
mounted behind the LEDs in the T8 tube. T8-tube reference designs
describing high-efficiency, non-isolated, high-power-factor (PF) LED
drivers. For more information, please click here.
Wireless Power Transmitters
Integrated Device Technology, Inc. announced the industry’s most
integrated wireless power transmitter solutions optimized for the Wireless
Power Consortium (WPC) Tx-A5, Tx-A6, and Tx-A11 configurations. The
new products expand IDT’s portfolio of WPC Qi-compliant magnetic
induction transmitters with solutions optimized for single-coil 5 V and
three-coil 12 V applications. The IDTP9035 and IDTP9036 are highefficiency,
feature-rich wireless power transmitters. The IDTP9035 is
designed to meet the requirements of the WPC Tx-A5 and Tx-A11 (5
V) specifications, while the IDTP9036 is designed to meet the WPC
Tx-A6 (12 V) specification. The IDTP9035 is optimized for a single-coil
configuration with a standard 5V supply input, allowing customers to
reduce their bill-of-materials (BOM) with cost-effective, low-voltage
power adaptors. For more information, please click here.
World’s lowest power capacitive
sensors with auto-calibration
NXP is a leader in low power capacitance touch sensors, which work based
on the fact that the human body can serve as one of the capacitive plates in
parallel to the second plate, connected to the input of the NXP capacitive
sensor device.
Thanks to a patented auto-calibration technology, the capacitive sensors
can detect changes in capacitance and continually adjust to the environment.
Things such as dirt, humidity, freezing temperatures, or damage to the
electrode do not affect the device function.
The rise of touch sensors in modern electronics has become a worldwide
phenomenon, and with NXP’s low power capacitive sensors it’s never been
easier to create the future.
