CYV15G0100EQ

Equalizer Operation

MCLADJ

The CYV15G0100EQ is a high speed adaptive cable equalizer designed to equalize standard definition (SD) and high definition (HD) serial digital interface (SDI) video data streams. The CYV15G0100EQ equalizer is optimized to equalize up to 175m of Canare L-5CFB and Belden 1694A cable at 270 Mbps and up to 70m of Canare L-5CFB and Belden 1694A cable at 1.485 Gbps. The CYV15G0100EQ equalizer contains one power supply and typically consumes 160 mW power at 3.3V. The multi rate equalizer meets the SMPTE 259M, SMPTE 292M, SMPTE 344M, and DVB-ASI video standards. It meets all pathological requirements for SMPTE 292M as defined by RP198 and for SMPTE 259M as defined by RP178. The CYV15G0100EQ Prosumer video cable equalizer is auto adaptive from 143 Mbps to 1.485 Gbps.

The CYV15G0100EQ equalizer has variable gain and multiple equalization stages that reverse the effects of the cable. This equalization is achieved by separate regulation of the lower and higher frequency components in the signal to give a clean output eye diagram. The CYV15G0100EQ has DC restoration for compensating the DC content of the SMPTE pathological patterns.

SDI, SDI

The CYV15G0100EQ accepts single-ended or differential serial video data streams over 75Ω coaxial cable. It is recommended to AC couple the SDI and SDI inputs as they are internally biased to 1.2V.

SDO, SDO

The CYV15G0100EQ has differential serial output interface drivers that use current mode logic (CML) drivers to provide source matching for the transmission line. These outputs are either AC coupled or DC coupled to the HOTLink II SerDes device.

CLI

Cable Length Indicator (CLI) is an analog output that gives an output voltage proportional to the equalized cable length. CLI gives an approximation of the length of cable at the differential serial inputs (SDI, SDI). CLI works at high definition (HD) data rates and standard definition (SD) data rates. The graph in Figure 3 on page 7 illustrates the CLI output voltage at various Belden 1694A cable lengths. With an increase in cable length, CLI output voltage decreases.

Maximum Cable Length Adjust (MCLADJ) sets the approximate maximum amount of cable to be equalized. MCLADJ works at SD and HD data rates.

If the MCLADJ voltage is greater than the CLI output voltage, the CD pin is driven HIGH and the outputs are muted. If the MCLADJ voltage is less than CLI voltage, then the equalizer’s CD pin is driven LOW and the incoming data stream is equalized. The graph in Figure 2 on page 7 illustrates the voltage required at MCLADJ input to equalize various Belden 1694A cable lengths for SD and HD data rates.

If MCLADJ functionality is not needed, then this pin should be left floating or tied to ground to allow maximum equalized cable length.

CD/MUTE

Carrier Detect/MUTE (CD/MUTE) is a bidirectional pin that provides an indication of the signal present at the equalizer’s input or it controls the muting of the equalizer’s output. The (CD/MUTE) operates for both HD and SD data rates.

If CD/MUTE is used as an output and the incoming data stream is not present or the cable length exceeds the length that is set by MCLADJ, the voltage at the CD/MUTE output is greater than 2.8V. If CD/MUTE is used as an output, the incoming data stream is present and the cable length does not exceed the length that is set by MCLADJ, then the voltage at the CD/MUTE output is less than 0.8V.

If CD/MUTE is used as an input and is set LOW, the equalizer serial outputs are not muted. If the CD/MUTE is used as an input and is set HIGH, then the equalizer serial outputs are muted.

When an invalid signal or a signal transmitted with a launch amplitude of less than 500 mV at HD data rates is received, the equalizer’s serial outputs are muted.

BYPASS

The CYV15G0100EQ has a bypass mode that enables the user to bypass the equalizer’s equalization and DC restoration functions. When the bypass mode 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 differential serial outputs (SDO, SDO).

In equalizer bypass mode, CD/MUTE is not functional.

AGC

Place a capacitor of 1 μF between the AGC± pins of the CYV15G0100EQ equalizer.
