LMH0307 3 Gbps HD/SD SDI Dual Cable Driver with Cable Detect
PRELIMINARY
June 26, 2008
LMH0307
3 Gbps HD/SD SDI Dual Cable Driver with Cable Detect
General Description
The LMH0307 3 Gbps HD/SD SDI Dual Cable Driver with
Cable Detect is designed for use in SMPTE 424M, SMPTE
292M, SMPTE 344M, and SMPTE 259M serial digital video
applications. The LMH0307 implements two complementary
output drivers and drives 75鈩?transmission lines (Belden
1694A, Belden 8281, or equivalent) at data rates up to 2.97
Gbps.
The LMH0307 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 LMH0307 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 LMH0307 is powered from a single 3.3V supply. Power
consumption is typically 230 mW in SD mode and 275 mW in
HD mode. The LMH0307 is available in a 16-pin LLP pack-
age.
The LMH0307 interfaces with National's LMH0356 for addi-
tional system control and power consumption savings (see
Typical Application).
