Notes:
1. Device performance is optimized for standard data rates (SD = 270Mb/s, HD = 1.485Gb/s, 3G = 2.970Gb/s, 6G = 5.94Gb/s).
2. 0m cable length.
3. All parts are production tested. In order to guarantee maximum jitter over the full range of specification (V_{CC_A} = +3.3V ±5%, T_A = -40°C to +85°C,
and 720-880mV_pp launch swing from the SDI cable driver), the recommended applications circuit must be used.
4. Based on validation data using the recommended applications circuit, with V_{CC_A} = +3.3V, T_A = -40°C to +85°C and 800mV_pp launch swing from
the SDI cable driver.
5. GAIN_SEL = 0.
