Christian Dupont, CEO of poLight, said, “Besides the integrated charge pump that provides sufficient voltage to activate the TLens™, Semtech’s driver’s main features are its small size, low power and optimized performance, which are essential factors when combined with poLight TLens™. The Semtech driver is suitable for different types of new imaging applications enabled by the TLens™ Autofocus speed.”

Semtech announced the availability of its SX8750 driver for capacitive and piezoelectric actuators targeting next generation Mobile Phone and PC camera modules. The SX8750, optimized for the poLight TLens™’s new technology, enables faster auto-focus, enhanced image quality and a smaller form factor camera module. The SX8750 platform combines high voltage and ultra-fast driver technology with ultra-low current consumption from 3V with no external coil. These unique features combine to drive MEMS based actuators for a larger camera resolution and a true real-time auto-focus, now up to 20x faster than traditional VCM technology, at a fraction of the power consumption.

Semtech’s complete line of cable drivers support today’s most demanding applications including 12G UHD-SDI, 6G UHD-SDI, 3G-SDI, HD-SDI, and SD-SDI. Our UHD-SDI cable drivers feature multi-rate operation up to 11.88Gbps, integrated reclocking for the lowest output jitter, input trace equalization, advanced signal integrity diagnostics,.

“By joining forces with poLight in the launch of TLens™’s new technology, we wanted to push the boundaries of camera modules,” said Marc Pegulu, Senior Marketing Director for Semtech Wireless & Sensing Products. “The TLens™ associated to our driver will change the imaging and video user experience and open new, real-time video applications for further advancements in the Mobile market.”

Key Features

• 2.65 - 3.6 V supply, -16 V to +30 V differential output
• Low power with less than 5mW averaged in active mode and with 1 uA listen mode current consumption
• Small form factor: CSP 0.8x1.6x0.5mm
• No coil or flying capacitor required for minimal total solution area
• I2C controlled 10 bit differential DAC for precise focus
• Low Interference thanks to lowest current consumption
• Allows for 1 ms settling time with TLens™

Applications

• Mobile and Smart Phone Camera Module
• Video Conference Call Camera Module

Availability

The SX8750 is sampling now and will be available in September in production quantities of 3,000-piece lots. Semtech offers comprehensive design assistance, including field- and factory-based support.

Semtech SX1276 Driver Bug

Dear Semtech team,

Drivers nxp input devices input. I have been struggling to make your SX1276 driver (as is shown in the tools section of the official web page outlining the features of the SX1276 on semtech.com) work as intended in FSK mode.

After setting the chip to Rx mode using Radio.Rx(0) (meaning that it should be in continuous RX mode) I am getting DIO0 interrupts with RegOpMode 13 (indicating that it is currently in TX mode) and IrqReg2 indicating that Fifo is empty. Note that this seems to happen at random times. But after appearance of this behavior, resetting the radio won't put the radio into defined state (register still reads the same). Note that reset signal is known to be present and is known to be implemented correctly.

Are recommended practices (like checking PLL or other internal blocks for having configured themselves after setting rx mode) followed in the official driver implementation, or does the user need to take care of it him/herself?

I am experiencing extensive problems considering the usage of the driver at packet rates above 210/second (of which 2/3 are tx and 1/3 is rx).

Radio settings are as follows:

Following functions are called to set receiver and transmitter parameters:

The CustomInit function referenced in the code is as follows:

Please note that the init function has been adjusted to account for first time settings (setting event callback functions):

Thank you for your answer in advance.

With kind regards from Germany

Edit:

I need to correct that the radio is NOT in TX mode upon interrupt, but in RX mode. Still, DIO0mapping is set to PayloadReady and an interrupt gets generated with bits CRCok and PayloadReady (fifo state) bits in IrqReg2 are not set.
