April 11, 2012 LMH0366 3 Gbps HD/SD SDI Low Power Reclocker with Integrated Eye Monitor General Description Features The LMH0366 3 Gbps HD/SD SDI Low Power Reclocker with Integrated Eye Monitor retimes serial digital video data conforming to the SMPTE 424M, SMPTE 292M, and SMPTE 259M-C standards. The reclocker operates at serial data rates of 125 Mbps, 270 Mbps, 1.4835 Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps. The LMH0366 automatically detects the incoming data rate and retimes the data to suppress accumulated jitter. The reclocker recovers the serial data-rate clock and optionally provides it as an output. The LMH0366 input has an FR4 equalizer capable of equalizing 0-60” of FR4 trace length, and also includes signal detection with a programmable threshold. The LMH0366 has two differential serial data outputs and offers flexibility in selecting the output signals between the reclocked data, recovered clock, or bypassed data. The output drivers offer programmable de-emphasis for up to 40” of FR4 trace losses, in addition to programmable common mode voltage and swing for flexible interfacing. The LMH0366 provides a 64 x 64 point eye monitor for analyzing the eye quality of the incoming signal. The LMH0366 supports two modes of operation. In pin mode, the LMH0366 operates with control pins to set its operating state. In SPI mode, an optional SPI serial interface can be used to configure and monitor multiple LMH0366 devices in a daisy-chain configuration. ■ SMPTE 424M, SMPTE 292M, and SMPTE 259M-C ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ compliant Supports 125 Mbps, 270 Mbps, 1.4835 Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps serial data rate operation Supports DVB-ASI at 270 Mbps and MADI at 125 Mbps 100 mW typical power consumption (145 mW with both output drivers enabled) Input equalization (0-60” FR4) and input signal detection Two differential, reclocked outputs with option of recovered clock Output de-emphasis to compensate for up to 40” of FR4 trace losses 64 x 64 point eye opening monitor 27 MHz external reference or referenceless operation Optional SPI register access Internally terminated 100Ω input with rail-to-rail input common mode voltage Internally terminated 100Ω LVDS outputs with programmable output common mode voltage and swing Single 2.5V supply operation Power save mode with device power down control 24-pin LLP package (4 x 4 mm) Industrial temperature range: -40°C to +85°C Applications ■ SMPTE 424M, SMPTE 292M, and SMPTE 259M serial digital interfaces ■ Broadcast video routers, switchers, and distribution amplifiers Typical Application 30173601 © 2012 Texas Instruments Incorporated 301736 SNAS585 www.ti.com LMH0366 3 Gbps HD/SD SDI Low Power Reclocker with Integrated Eye Monitor PRELIMINARY LMH0366 Physical Dimensions inches (millimeters) unless otherwise noted 24-Pin LLP Order Number LMH0366SQ Package Number SQA24A www.ti.com 2 LMH0366 Notes 3 www.ti.com LMH0366 3 Gbps HD/SD SDI Low Power Reclocker with Integrated Eye Monitor Notes www.ti.com IMPORTANT NOTICE Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements, and other changes to its products and services at any time and to discontinue any product or service without notice.
