NOTES:
1. 0m cable length.
2. All parts production tested. In order to guarantee jitter over the full range of specification (VCC = 3.3V ±5%, TA = 0°C to 70°C, and
720-880mV launch swing from the SDI cable driver) the recommended applications circuit must be used.
3. Tested on CB1574A board from 5MHz to 2GHz.
4. Based on characterization data using the recommended applications circuit, at VCC = 3.3V, TA = 25°C, and 800mV launch swing from the SDI
cable driver.
5. Equalizer Pathological test signal is used.
