3Gbps HD/SD SDI Cable Driver

Check for Samples: LMH0302

FEATURES

DESCRIPTION

The LMH0302 3Gbps HD/SD SDI Cable Driver is

• SMPTE 424M, SMPTE 292M, SMPTE 344M, and

designed for use in SMPTE 424M, SMPTE 292M,

SMPTE 259M Compliant

SMPTE 344M, and SMPTE 259M serial digital video

• Data Rates to 2.97 Gbps

applications. The LMH0302 drives 75Ω transmission

• Supports DVB-ASI at 270 Mbps

lines (Belden 1694A, Belden 8281, or equivalent) at

data rates up to 2.97 Gbps.

• Differential Input

The LMH0302 provides two selectable slew rates for

• 75Ω Differential Output

SMPTE 259M and SMPTE 424M / 292M compliance.

• Selectable Slew Rate

The output driver may be powered down via the

• Output Driver Power Down Control

output driver enable pin.

• Single 3.3V Supply Operation

The LMH0302 is powered from a single 3.3V supply.

• Industrial Temperature Range: −40°C to +85°C

Power consumption is typically 125 mW in SD mode

and 165 mW in HD mode. The LMH0302 is available

• Typical Power Consumption: 125 mW in SD

in a 16-pin WQFN package.

Mode and 165 mW in HD Mode

• 16-pin WQFN Package

• Footprint Compatible With the LMH0002SQ

• Replaces the Gennum GS2978

APPLICATIONS

• SMPTE 424M, SMPTE 292M, SMPTE 344M, and

SMPTE 259M Serial Digital Interfaces

• Digital Video Routers and Switches

• Distribution Amplifiers
