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.

•

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

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.
