Functional Description
The CYV270M0104EQ is an adaptive video cable equalizer
designed to equalize and restore signals received over 75Ω
coaxial cable. The equalizer is designed to meet SMPTE 259M
data rates and is optimized for performance at 270 Mbps. The
CYV270M0104EQ is optimized to equalize up to 350m of Belden
1694A and Canare L-5CFB coaxial cable at 270 Mbps. The
CYV270M0104EQ connects seamlessly to the HOTLink II family
of transceiver devices and HOTLink receiver devices.
The CYV270M0104EQ has DC restoration to compensate for
the DC content of the SMPTE pathological patterns. The
maximum cable length adjust (MCLADJ) sets the approximate
maximum cable length to equalize. The CYV270M0104EQ’s
differential serial outputs (SDO, SDO) mute, when the approx-
imate cable length set by MCLADJ is reached and carrier detect
(CD) is tied to MUTE. The MUTE pin controls muting of the
equalizer outputs.
Power consumption is typically 160 mW at 3.3V.
