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