am looking for general purpose serializer that can directly connect to Altera FPGA transceiver. It should have 20 parallel inputs at 100MHz, and serialized into a single lane .
Is the SCAN12100 is the right and only solution?
Two other options would be the TLK6002 or the FPGA-Link Ser/Des (DS32EL0421).
In addition to the TLL6002 and DS32EL0421, we also have TLK2541 that can support a 20bit input at 100MHz.
Looks that The TLK2541 will do the job.
How can I verify that it can interface with Altera’s Stratix IV transceivers?
Also I need the signals to run over 2 meter cable with twisted pairs, is it suitable?
The customer can evaluate the the TLK2541 with FPGA by building a test board but this may be too much work. If the customer is concerned about interface level interoperability, then often customers model the interface using IBIS models. I have attached the IBIS model for the TLK2541.
TLK2541 should be able to drive 2m of twisted pair cable such as twin-ax or cat5 cable. Please note that cable loss, connector loss, and the application's sensitivity to jitter will determine how long any particular cable can be driven.
