Functional Description
The CYV15G0104EQ is a multi rate adaptive equalizer designed
to equalize and restore signals received over 75Ω coaxial cable.
The equalizer meets SMPTE 292M, SMPTE 344M, and SMPTE
259M data rates. The CYV15G0104EQ is optimized to equalize
up to 350m of Canare L-5CFB and Belden 1694A coaxial cable
at 270 Mbps and typically up to 200m of Canare L-5CFB and
Belden 1694A coaxial cable at 1.485 Gbps. The
CYV15G0104EQ connects seamlessly to the HOTLink II family
of transceiver devices.
The CYV15G0104EQ 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 at SD and HD data rates. The
CYV15G0104EQ’s differential serial outputs (SDO, SDO
) mute,
when the approximate cable length set by MCLADJ is reached,
and carrier detect (CD) is tied to MUTE. MUTE pin controls
muting the outputs of the equalizer at HD and SD data rates.
Power consumption is typically 160 mW at 3.3V.

Table 1. Pin Descriptions - CYV15G0104EQ Single Channel Cable Equalizer
Name IO Characteristics Signal Description
Control Signals
MUTE LVTTL Input Mute.
When the MUTE pin is set LOW, the equalizer’s differential serial outputs are not muted.
When the MUTE pin is set HIGH, the equalizer’s differential serial outputs are muted.
BYPASS setting is ignored when MUTE is HIGH.
Connecting CD
to MUTE pin enables automatic muting of the equalizer upon loss of signal.
Do not leave unused MUTE pin floating. Always drive it to a known state.
CD LVTTL Output Carrier Detect.
When the incoming data stream is present and maximum cable length does not exceed
that set by MCLADJ, CD
outputs a voltage less than 0.8V.
When the incoming data stream is not present or maximum cable length exceeds that set
by MCLADJ, CD
outputs a voltage greater than 2.8V.
Connecting CD
to MUTE pin enables automatic muting of the equalizer upon loss of signal.
MCLADJ Analog Input Maximum Cable Length Adjust.
The maximum equalized cable length is set by the voltage applied to the MCLADJ input.
When the maximum cable length set by MCLADJ is reached, the CD
indicator is
deasserted.
If MCLADJ functionality is not needed, this pin should be left floating or tied to ground to
allow maximum equalized cable length.
MCLADJ works at both SD and HD data rates.
BYPASS LVTTL Input Equalizer Bypass. When BYPASS is set HIGH, the signal presented at the equalizer’s
differential serial inputs (SDI, SDI
) is routed to the equalizer’s differential serial outputs
(SDO, SDO
) without equalizing.
When BYPASS is set LOW, the incoming video data stream is equalized and presented
at the equalizer‘s serial differential outputs (SDO, SDO
).
When MUTE pin is set HIGH, BYPASS setting is ignored and the serial outputs are muted.
AGC, AGC Analog Automatic Gain Control. Place a capacitor of 1 μF between the AGC and AGC pins.
SDO, SDO Differential
Output
Differential Serial Outputs. The equalized serial video data stream is presented at the
SDO/SDO
differential serial CML output.
SDI, SDI Differential
Input
Differential Serial Inputs. SDI/SDI accepts either a single-ended or differential serial
video data stream over 75Ω coaxial cable.
