some sellers propose CY22801KSXC-024 ICs,
when I wrote this post and filled the field 'Associated Product', CY22801SXC-038 was automatically proposed as one of selectable product in the list.
What -024 and -038 mean?
In datasheet these parameters mean 'Custom Configuration Code (Only for Factory Programmable Devices)'.
Is it possible to find the frequencies for these ICs?
under Fref = ??? MHz
CLKA = ... MHz, CLKB = , CLKC= .
Do we have replacement for LVDS-CMOS Output Low power clock fanout buffer equivalent to ADCLK846BCPZ.
I redesign and old design with CY7B9950AXI.
CY7B9950AXI is discontinued, do you have any replacement or any other recommendation of Multi-Phase PLL Clock Buffer
I am looking for an alternative component to the CY25823. The component must not be pin compatible, but function compatible.
Does anybody know an alternative or the possibility to reproduce this component.

Regarding CY27410FLTXI(TRAY) and CY27410FLTXIT(Tape and Reel),
Please let us know TRAY specification and Tape and Reel Specification.
Its Device Package is PG-VQFN-48 (48-Pin QFN (7 × 7 × 1.00 mm) LT48D 5.6 × 5.6 E-Pad (Sawn) Package)

I'm writing an IIO driver in C for the Cypress CY22801, with communications via I2C.
However, setting the two available output clock channels generically will be difficult, as there are a lot of variables involved.
For example, I will have to calculate the values for PB, PO, Q, and DIVxN, and select the most suitable divider channel (1/2), and set the source controls for the clock outputs, for each clock output - each will affect the other one, also.
i.e. CLK_OUT_X = (2 * (pb + 4) + po) / (q + 2) / DIVxN * CLK_INPUT_FREQ
The CyClocksRT software generates all of this information automatically. Is the source code for this component of the software available, please? Or can a version of this be provided to aid our use of your products?
Hi. I'm looking for the programming interface and adapter to in house program the CY22394. It looks like the Cpress Programming kits are obsolete. Is there a ne one available, or where can I find information on how to program in house.
I'm using the CY22801 clock synthesiser on a project with a Xilinx Zynq SoC and Yocto.
I'm developing a C driver and IIO wrapper for use with Linux.
However, I'm not getting a response from the IC via I2C as it seems to be pulling on the SCL line.
Pin 3 (SDAT / FS0 / VCXO / OE / PD# - serial interface data line / frequency select 0 / VCXO analog control voltage / Output Enable / Power-down) and pin 5 (CLKB / FS1 / SCLK - clock output B / frequency select 1 / serial interface clock line) are multi-function pins. How am I supposed to configure this IC for use with I2C?
