The LMH0202 drives 75Ω transmission lines (Belden 8281, Belden 1694A or equivalent) at data rates up to 1.485 Gbps. 1 2 • • • • • • • • SMPTE 292M, SMPTE 344M and SMPTE 259M Compliant Data Rates to 1.485 Gbps Dual Differential Inputs Dual 75Ω Differential Outputs Two Selectable Slew Rates Adjustable Output Amplitude Single 3.3V Supply Operation Commercial Temperature Range: 0°C to +70°C Typical Power Consumption: 250 mW in SD Mode and 300 mW in HD Mode The LMH0202 provides two selectable slew rates for SMPTE 259M and SMPTE 292M compliance. The output voltage swing is adjustable via a single external resistor. The LMH0202 offers the flexibility to implement either dual differential inputs or a single differential input (externally routed via PCB) to dual differential outputs. The latter option provides an ideal solution for DVB-ASI applications where only the non-inverted outputs are typically used.

DEVICE OPERATION INPUT INTERFACING The LMH0202 accepts either differential or single-ended input. 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.

This provides a solution for DVB-ASI applications where two non-inverted outputs are needed. LMH0202 1.0 PF 25: SDI1 50: SDI1 25: 25: Differential Input 1.0 PF 50: SDI2 SDI2 25: 0.1 PF Figure 3. Single Differential Input for DVB-ASI OUTPUT INTERFACING The LMH0202 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 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. OUTPUT SLEW RATE CONTROL The LMH0202 output rise and fall times are selectable for either SMPTE 259M or SMPTE 292M compliance via the SD/HD pin. For slower rise and fall times, or SMPTE 259M compliance, SD/HD is set high. For faster rise and fall times, or SMPTE 292M compliance, SD/HD is set low. 6 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: LMH0202 LMH0202 www.ti.com SNLS212C – FEBRUARY 2006 – REVISED APRIL 2013 REVISION HISTORY Changes from Revision B (April 2013) to Revision C • Page Changed layout of National Data Sheet to TI format ............................................................................................................ 6 Submit Documentation Feedback Copyright © 2006–2013, Texas Instruments Incorporated Product Folder Links: LMH0202 7 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) LMH0202MT/NOPB ACTIVE TSSOP PW 16 92 RoHS & Green SN Level-1-260C-UNLIM 0 to 70 L202 (1) The marketing status values are defined as follows: ACTIVE: Product device recommended for new designs.
