The equalizer operates over a wide and 400 Meters at 270 Mbps range of data rates from 125 Mbps to 2.97 Gbps and supports ST 424, ST 292, ST 344, ST 259, and DVB- • Ultra-low Power Consumption: 140 mW (Dual ASI standards. Outputs), 115 mW (Single Output) • Dual Differential Outputs; Second Output Can Be The LMH0395 device provides extended cable reach with improved immunity to crosstalk and ultra low Independently Powered Down power consumption. The equalizer includes active • Power-Save Mode With Auto Sleep Control (17- sensing circuitry that ensures robust performance and mW Typical Power Consumption in Power-Save enhanced immunity to variations in the input signal Mode) launch amplitude. The LMH0395 offers power • Designed for Crosstalk Immunity management to further reduce power consumption when no input signal is present. • Output De-Emphasis to Compensate for FR4 Board Trace Losses The LMH0395 has two differential serial data outputs, • Digital and Analog Programmable MUTEREF increasing flexibility and eliminating the need for a fanout buffer on the output in many applications. The Threshold outputs may be independently enabled and • Optional SPI Register Access and Pin Mode controlled. The output drivers offer programmable de- Operation emphasis for up to 40 inches of FR4 trace losses. • Input Data Rates: 125 Mbps to 2.97 Gbps The LMH0395 supports two modes of operation. In pin mode, the LMH0395 operates with control pins to • Internally Terminated 100- Ω LVDS Outputs With set its operating state. In SPI mode, an optional SPI Programmable Output Common-Mode Voltage serial interface can be used to access and configure and Swing multiple LMH0395 devices in a daisy-chain • Programmable Launch Amplitude Optimization configuration. • Cable Length Indicator Device Information(1) • Single 2.5-V Supply Operation PART NUMBER PACKAGE BODY SIZE (NOM) • 24-Pin WQFN Package LMH0395 WQFN (24) 4.00 mm × 4.00 mm • Industrial Temperature Range: −40°C to +85°C (1) For all available packages, see the orderable addendum at the end of the data sheet. 2 Applications • ST 424, ST 292, ST 344, and ST 259 Serial Functional Block Diagram Digital Interfaces(1) • Broadcast Video Routers, Switchers, and Distribution Amplifiers (1) Due to SMPTE naming convention, all SMPTE Engineering Documents will be numbered as a two-letter prefix and a number. Documents and references with the same root number and year are functionally identical; for example ST 424-2006 and SMPTE 424M-2006 refer to the same document. 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
