21 / 125 page ![]() GS2972 3G/HD/SD-SDI Serializer with Complete SMPTE Audio & Video Support Final Data Sheet Rev. 9 GENDOC-047479 September 2013 21 of 125 www.semtech.com 2.3 DC Electrical Characteristics Operating Temperature Range– – -20 – 85 °C 2 Functional Temperature Range– – -40 – 85 °C 2 Notes: 1. This is 0.7V rather than 1.2V because there is a voltage drop across an external 105 Ω resistor. See Typical Application Circuit. 2. Operating Temperature Range guarantees the parameters given in the DC Electrical Characteristics and AC Electrical Characteristics. Functional Temperature Range guarantees a device start-up. Table 2-2: Recommended Operating Conditions (Continued) Parameter Symbol Conditions Min Typ Max Units Note Table 2-3: DC Electrical Characteristics VCC = +3.3V ±5%, TA = -20°C to +85°C, unless otherwise shown Parameter Symbol Conditions Min Typ Max Units Note System +1.2V Supply Current I1V2 10bit 3G − 135 200 mA − 20bit 3G − 135 200 mA − 10/20bit HD − 100 160mA − 10/20bit SD − 75 120 mA − DVB_ASI − 75 120 mA − +1.8V Supply Current I1V8 10bit 3G − 15 30 mA − 20bit 3G − 15 32 mA − 10/20bit HD − 15 32 mA − 10/20bit SD − 310 mA − DVB_ASI − 310 mA − +3.3V Supply Current I3V3 10bit 3G − 90 110 mA − 20bit 3G − 90 110 mA − 10/20bit HD − 90 110 mA − 10/20bit SD − 70 90 mA − DVB_ASI − 70 90 mA − Total Device Power (IO_VDD = +1.8V) P1D8 10bit 3G − 400 560mW − 20bit 3G − 400 560mW − 10/20bit HD − 350 510 mW − 10/20bit SD − 300 450 mW − DVB_ASI − 300 450 mW − Reset − 200 − mW − Standby − 110 180 mW 1 |
