DS90LT012A: naming conventions

Part Number: DS90LT012A
Other Parts Discussed in Thread: DS90LV031A, DS90LV032A, CDCLVD2106, SN65LVDS108

I have few questions:

Is there a naming convention related to ANSI TIA/EIA-644-A and ANSI TIA/EIA-644 compatibility? For example, DS90LV031a, DS90LV032a Transmit and Receive pair are ANSI TIA/EIA-644 Standard compatible, DS90LT011AQ, DS90LT012ATLD Transmit and Receive pair are ANSI TIA/EIA-644-A Standard compatible.

Is there a special meaning between LV and LT?

We need a 6 channel LVDS Buffer. I can only find CDCLVD2106 which operates at 2.5V. Is there a 3.3V version?

Hi Michael,

1. There's no special naming convention related to TIA/EIA-644-A and TIA/EIA-644 standard.

2. If the device is a receiver, LV means there's no integrated termination resistor while LT means there is an integrated termination resistor. No special meanings beyond that.

3. CDCLVD2106 looks like a 1:6 buffer from the clocking group. For a similar device for general purpose applications there is the SN65LVDS108.

I.K.

Thanks I.K.

Some More questions really quick:

What is the difference between DS90LV011 and DS90LV031?
Understand SNs are Ti part numbers. Is there a cross reference between the DSs and the SNs?
Is there a TIA/EIA-644-A counterpart for every TIA/EIA-644 parts?
