Description
The 270 field programmable VCXO clock synthesizer generates up to eight high-quality, high-frequency clock outputs including multiple reference clocks from a low-frequency crystal input. It is designed to replace crystals and crystal oscillators in most electronic systems. Using IDT's VersaClockTM software to configure PLLs and outputs, the 270 contains a One-Time Programmable (OTP) ROM for field programmability. Programming features include VCXO, eight selectable configuration registers and up to two sets of four low-skew outputs. Using Phase-Locked Loop (PLL) techniques, the device runs from a standard fundamental mode, inexpensive crystal, or clock. It can replace VCXOs, multiple crystals and oscillators, saving board space and cost. The 270 is also available in factory programmed custom versions for high-volume applications.

Notification congestion control
Hi I have DA14580 board with a sensor that samples at a rate of 25Hz. The data is send to a central device through notification at the same rate. The max connection interval is set to 40ms, and it works pretty well at first. However if the central is moved ...

How are error count value of B2ECT register and BER related in UPD98404?
One to 24 B2 errors are detected in 1 frame. The B2ECT register adds up the detection error count for each frame and stores the cumulative count of detected errors from the preceding read until the current read. The bit count of one STM-1 frame is as follows. 270byte ...

RA Family: How to adjust touch panel input coordinates when display orientation is changed
... src/touch_gt911.c. Depending on the Display Orientation setting, the .transform_flags settings are as follows: .transform_flags = (TOUCH_GT911_COORD_ROTATE_X | TOUCH_GT911_COORD_ROTATE_Y), // Flip (180) .transform_flags = (TOUCH_GT911_COORD_ROTATE_Y | TOUCH_GT911_COORD_EXCHANGE), // Counter-clockwise (270)
