NOTES:
1. 0m cable length.
2. All parts are production tested. In order to guarantee jitter over the full range of specification (V_CC = 3.3V ±5%, T_A = -20°C to +85°C, and
720-880mV launch swing from the SDI cable driver) the recommended applications circuit must be used.
3. Based on characterization data using the recommended applications circuit, at V_CC = 3.3V, T_A = 25°C and 800mV launch swing from the SDI
cable driver.
4. Tested on a Semtech evaluation board from 5MHz to 3GHz.
