DescriptionThe LMH0346 is 3 Gbps HD/SD SDI Reclocker with Dual Differential Outputs. It operates at serial data rates of 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps. The device is powered from a single 3.3V supply and is available in two spacesaving packages: a 6.5 X 4.4 mm 20-pin e-TSSOP and an even more spaceefficient 5 X 4 mm 24-pin LLP package.
The features of LMH0346 can be summarized as:(1)Supports SMPTE 424M, SMPTE 292M, and SMPTE 259M (C) serial digital video standards; (2)Supports 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps serial data rate operation; (3)Supports DVB-ASI at 270 Mbps; (4)Single 3.3V supply operation; (5)370 mW typical power consumption; (6)Two differential, reclocked outputs; (7)Choice of second reclocked output or low-jitter, differential, data-rate clock output; (8)Single 27 MHz external crystal or reference clock input; (9)Manual or automatic rate select input; (10)SD/HD operating rate indicator output; (11)Lock Detect indicator output; (12)Output mute function for data and clock; (13)Auto/Manual reclocker bypass; (14)Differential LVPECL compatible serial data inputs and outputs; (15)LVCMOS control inputs and indicator outputs; (16)20-pin e-TSSOP or 24-pin LLP package; (17)Industrial temperature range: -40°C to +85°C; (18)Footprint compatible with the LMH0046 andLMH0026 (e-TSSOP package).
The absolute maximum ratings of LMH0346 are:(1)Supply Voltage (VCCVEE):4.0V; (2)Logic Supply Voltage (Vi):VEE-0.15V to VCC+0.15V; (3)Logic Input Current (single input):Vi = VEE-0.15V..-5 mA,Vi = VCC+0.15V..+5 mA; (4)Logic Output Voltage (Vo):VEE-0.15V to VCC+0.15V; (5)Logic Output Source/Sink Current:±8 mA; (6)Serial Data Output Sink Current (ISDO):24 mA; (7)Package Thermal Resistance:JA 20-pin e-TSSOP..26.6°C/W,JA 24-pin LLP..33.0 °C/W,JC 20-pin e-TSSOP..2.4°C/W,JC 24-pin LLP..3.2°C/W; (8)Storage Temp. Range:-65°C to +150°C; (9)Junction Temperature:+125°C; (10)Lead Temperature (Soldering 4 Sec):+260°C (Pb-free); (11)ESD Rating (HBM):8 kV; (12)ESD Rating (MM):400V; (13)ESD Rating (CDM):2kV.
