Current flow out of device pins is defined as negative. All voltages are stated referenced to VEE = 0 Volts. (2) Typical values are stated for VCC = +3.3V and TA = +25°C. (3) Specification is ensured by characterization. (4) This specification is for 0m cable only.

(2) Based on characterization data over the full range of recommended operating conditions of the device. Jitter is measured in accordance with SMPTE RP 184, SMPTE RP 192, and the applicable serial data transmission standard: SMPTE 424M, SMPTE 292M, or SMPTE 259M. (3) Measured with Pseudo Matrix Pathological test signal. (4) Specification is ensured by characterization. (5) Input return loss is dependent on board design. The LMH0344 exceeds this specification on the SD344 evaluation board with a return loss network consisting of an 8.2 nH inductor in parallel with a 0.5 pF capacitor in parallel with the 75 Ω series resistor on the input.
