The inputs are self-biased, allowing for simple AC or DC coupling. DC-coupled inputs must be kept within the specified common-mode range. SDI and SDI are selfbiased at approximately 2.1V with VCC = 3.3V. Figure 2 shows the differential input stage for SDI and SDI. VCC SDI SDI VCC 5 k: 10 k: 80: 10 k: 10 k: Figure 2. Differential Input Stage for SDI and SDI. OUTPUT INTERFACING The LMH0001 uses current mode outputs. Single-ended output levels are 800 mVP-P into 75Ω AC-coupled coaxial cable (with RREF = 750Ω). Output level is controlled by the value of the RREF resistor connected between the RREF pin and VCC. The RREF resistor should be placed as close as possible to the RREF pin. In addition, the copper in the plane layers below the RREF network should be removed to minimize parasitic capacitance. 4 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: LMH0001 LMH0001 www.ti.com SNLS276C – AUGUST 2007 – REVISED APRIL 2013 REVISION HISTORY Changes from Revision B (April 2013) to Revision C • Page Changed layout of National Data Sheet to TI format ............................................................................................................ 4 Submit Documentation Feedback Copyright © 2007–2013, Texas Instruments Incorporated Product Folder Links: LMH0001 5 PACKAGE OPTION ADDENDUM www.ti.com 10-Dec-2020 PACKAGING INFORMATION Orderable Device Status (1) Package Type Package Pins Package Drawing Qty Eco Plan (2) Lead finish/ Ball material MSL Peak Temp Op Temp (°C) Device Marking (3) (4/5) (6) LMH0001SQ/NOPB ACTIVE WQFN RUM 16 1000 RoHS & Green SN Level-1-260C-UNLIM -40 to 85 L001 LMH0001SQE/NOPB ACTIVE WQFN RUM 16 250 RoHS & Green SN Level-1-260C-UNLIM -40 to 85 L001 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
