Part Number: SCAN921224 Other Parts Discussed in Thread: ADC3549 , Hi there,
I am designing a system using the ADC3549 (14-bit, 500 MSPS). My goal is to serialize/deserialize the data to lower the pin count and data rate before reaching my processor…
Part Number: SCAN921224 Other Parts Discussed in Thread: SN65LV1023A Hi all
My customer has an application as illustrated in the below schematic where they are transferring data and an independent clock at 60MHz over a serial interface.
They might…
Part Number: SN65LV1023A Other Parts Discussed in Thread: SCAN921224 , SCAN921023 , , SN65LV1224B Good Day,
I'm using Serializer/Desirializer SCAN921023 and SCAN921224 respectively.
according to TI website the serializer (SCAN921023) is not recommended…
Hi Bart,
The frequency tolerance is actually calculated as 28.8 MHz * 100/(1e6) = 0.0028. So, the max should be 28.80 MHz, and the minimum is 28.797 MHz. Your refclk is outside of datasheet specification. Additionally, can you do the same measurement…
Hello Eric,
The SN651224B should be able to lock to random data. However, as you mentioned, it does require a REFCLK which is the same frequency as the transmit clock on the other side with +/-100ppm accuracy. The following app note discusses the differences…

I want to provide a forewarning here that the support for JTAG devices is limited, as the original National Semiconductor group who supported this product no longer exists, thus limiting our in-depth knowledge about this device.
SCANSTA112 would…

Hello Yunus,
Sorry for the late reply. Unfortunately, I am not sure why this is failing. Have they looked at the documents in the product folder (Reference Guide, etc.)? There is also another useful document that may be helpful (please see attached…
Hi Patrick,
Yes, the SCANSTA112 devices can be daisy-chained. If they are daisy-chained and connected to the same backplane, it is usually recommended to operate in Scanbridge mode, as the user will typically need a way to access/address each SCANSTA112…
