LMH0056 HD/SD SDI Reclocker with 4:1 Input Multiplexer

Check for Samples: LMH0056

FEATURES

DESCRIPTION

The LMH0056 HD/SD SDI Reclocker with 4:1 Input

Multiplexer retimes serial digital video data

conforming to the SMPTE 292M and SMPTE 259M

(A & C) standards. The LMH0056 operates at serial

data rates of 143 Mbps, 270 Mbps, 1.483 Gbps and

1.485 Gbps. The LMH0056 supports DVB-ASI

operation at 270 Mbps. The LMH0056 includes an

integrated 4:1 input multiplexer for selecting one of

four input data streams for retiming.

•

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

360 mW Typical Power Consumption

Integrated 4:1 Multiplexed Input

Two Differential, Reclocked Outputs

The LMH0056 automatically detects the incoming

data rate and adjusts itself to retime the incoming

data to suppress accumulated jitter. The LMH0056

recovers the serial data-rate clock and optionally

provides it as an output. The LMH0056 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.
