LMH0046 www.ti.com SNLS222F – APRIL 2006 – REVISED APRIL 2013 LMH0046 HD/SD SDI Reclocker With Dual Differential Outputs Check for Samples: LMH0046 FEATURES DESCRIPTION • The LMH0046 HD/SD SDI Reclocker retimes serial digital video data conforming to the SMPTE 292M and SMPTE 259M (A & C) standards. The LMH0046 operates at serial data rates of 143 Mbps, 270 Mbps, 1.483 Gbps and 1.485 Gbps. The LMH0046 supports DVB-ASI operation at 270 Mbps. 1 2 • • • • • • • • • • • • • • • • Supports SMPTE 292M and SMPTE 259M (A & C) Serial Digital Video Standards Supports 143 Mbps, 270 Mbps, 1.483 Gbps, and 1.485 Gbps Serial Data Rate Operation Supports DVB-ASI at 270 Mbps Single 3.3V Supply Operation 330 mW Typical Power Consumption Two Differential, Reclocked Outputs Choice of Second Reclocked Output or LowJitter, Differential, Data-Rate Clock Output Single 27 MHz External Crystal or Reference Clock Input Manual Rate Select Input SD/HD Operating Rate Indicator Output Lock Detect Indicator Output Output Mute Function for Data and Clock Auto/Manual Reclocker Bypass Differential LVPECL Compatible Serial Data Inputs and Outputs LVCMOS Control Inputs and Indicator Outputs 20-Pin HTSSOP Package Industrial Temperature Range: -40°C to +85°C The LMH0046 automatically detects the incoming data rate and adjusts itself to retime the incoming data to suppress accumulated jitter. The LMH0046 recovers the serial data-rate clock and optionally provides it as an output. The LMH0046 has two differential serial data outputs; the second output may be selected as a low-jitter, data-rate clock output. Controls and indicators are: serial clock or second serial data output select, manual rate select input, SD/HD rate indicator output, lock detect output, auto/manual data bypass and output mute. The serial data inputs, outputs, and serial data-rate clock outputs are differential LVPECL compatible. The CML serial data and serial data-rate clock outputs are suitable for driving 100Ω differentially terminated networks. The control logic inputs and outputs are LVCMOS compatible. The LMH0046 is powered from a single 3.3V supply. Power dissipation is typically 330 mW. The device is housed in a 20-pin HTSSOP package.
