LMH0303 3 Gbps HD/SD SDI Cable Driver with Cable Detect
PRELIMINARY
July 10, 2008
LMH0303
3 Gbps HD/SD SDI Cable Driver with Cable Detect
General Description
The LMH0303 3 Gbps HD/SD SDI Cable Driver with Cable
Detect is designed for use in SMPTE 424M, SMPTE 292M,
SMPTE 344M, and SMPTE 259M serial digital video appli-
cations. The LMH0303 drives 75鈩?transmission lines (Belden
1694A, Belden 8281, or equivalent) at data rates up to 2.97
Gbps.
The LMH0303 includes intelligent sensing capabilities to im-
prove system diagnostics. The cable detect feature senses
near-end termination to determine if a cable is correctly at-
tached to the output BNC. Input loss of signal (LOS) detects
the presence of a valid signal at the input of the cable driver.
These sensing features may be used to alert the user of a
system fault and activate a deep power save mode, reducing
the cable driver's power consumption to 3 mW. These fea-
tures are accessible via an SMBus interface.
The LMH0303 provides two selectable slew rates for SMPTE
259M and SMPTE 424M / 292M compliance. The output am-
plitude is adjustable 鹵10% in 5 mV steps via the SMBus.
The LMH0303 is powered from a single 3.3V supply. Power
consumption is typically 130 mW in SD mode and 155 mW in
HD mode. The LMH0303 is available in a 16-pin LLP pack-
age.
The LMH0303 interfaces with National's LMH0356 for addi-
tional system control and power consumption savings (see
Typical Application).
