FEATURES
DESCRIPTION
The LMH0046 HD/SD SDI Reclocker retimes serial
2
Supports SMPTE 292M and SMPTE 259M
digital video data conforming to the SMPTE 292M
(A & C) Serial Digital Video Standards
and SMPTE 259M (A & C) standards. The LMH0046
Supports 143 Mbps, 270 Mbps, 1.483 Gbps,
operates at serial data rates of 143 Mbps, 270 Mbps,
and 1.485 Gbps Serial Data Rate Operation
1.483 Gbps and 1.485 Gbps. The LMH0046 supports
DVB-ASI operation at 270 Mbps.
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
330 mW Typical Power Consumption
data to suppress accumulated jitter. The LMH0046
Two Differential, Reclocked Outputs
recovers the serial data-rate clock and optionally
Choice of Second Reclocked Output or Low-
provides it as an output. The LMH0046 has two
Jitter, Differential, Data-Rate Clock Output
differential serial data outputs; the second output may
be selected as a low-jitter, data-rate clock output.
Single 27 MHz External Crystal or Reference
Controls and indicators are: serial clock or second
