The equalizer is designed to meet SMPTE 292M, SMPTE 344M, and SMPTE 259M data rates. The CYV15G0102EQ is optimized to equalize up to 400m of Belden 1694A coaxial cable at 270 Mbps and up to 200m of Belden 1694A coaxial cable at 1.485 Gbps. The CYV15G0102EQ connects seamlessly to the HOTLink II family of transceiver devices. The CYV15G0102EQ has DC restoration for compensation of the DC content of the SMPTE pathological patterns. A cable length indicator (CLI) provides an indication of the cable length being equalized at HD-SDI and SD-SDI data rates. The Maximum cable length adjust (MCLADJ) sets the approximate maximum cable length to be equalized at SD and HD data rates. The CYV15G0102EQ's differential serial outputs (SDO, SDO) mute, when the approximate cable length set by MCLADJ is reached. CD/MUTE is a bidirectional pin that provides an indication of the signal being present at the equalizer inputs. It also controls muting the outputs of the equalizer at HD and SD data rates. Power consumption is typically 160 mW at 3.3V.

CLI works at both SD-SDI and HD-SDI data rates. Carrier Detect/Mute Indicator: Output: When the incoming data stream is present, the CD/MUTE outputs a voltage less than 0.8V. When the incoming data stream is not present, the CD/MUTE outputs a voltage greater than 3V. Input: When the CD/MUTE pin is tied to ground, the equalizer's differential serial outputs are not muted and the MCLADJ setting is overwritten. When the CD/MUTE pin is tied to VCC, the equalizer's differential serial outputs are muted and the MCLADJ setting is overwritten. MCLADJ Analog Input Maximum Cable Length Adjust: The maximum cable length to be equalized is set by the voltage applied to the MCLADJ input. When the maximum cable length set by MCLADJ is reached, the differential output is muted. MCLADJ works at both SD and HD data rates. Equalizer Bypass: When BYPASS is tied to VCC, the signal presented at the equalizer's differential serial inputs (SDI, SDI) is routed to the equalizer's differential serial outputs (SDO, SDO) without performing equalization. When BYPASS is tied to GND, the incoming video data stream is equalized and presented at the equalizer`s serial differential outputs (SDO, SDO). In equalizer bypass mode, CD/MUTE is not functional. BYPASS LVTTL Input AGC SDO, SDO SDI, SDI Analog Differential Output Differential Input Automatic Gain Control: A capacitor of 1 F should be placed between the AGC pins. Differential Serial Outputs: The equalized serial video data stream is presented at the SDO/SDO differential serial CML output. Differential Serial Inputs: SDI/SDI can accept either a single ended or differential serial video data stream over 75 coaxial cable. Power VCC GND Power Gnd +3.3V Power. Connect to Ground. by RP178. The CYV15G0102EQ multi-rate Cable Equalizer is auto-adaptive from 143 Mbps to 1.485 Gbps. The CYV15G0102EQ equalizer has variable gain, 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 eye. The CYV15G0102EQ has DC restoration for compensating the DC content of the SMPTE pathological patterns. Equalizer Operation The CYV15G0102EQ is a high-speed adaptive cable equalizer designed to equalize standard definition (SD) and high definition (HD) serial digital interface (SDI) video data streams. CYV15G0102EQ equalizer is optimized to equalize up to 400m of Belden 1694A cable at 270 Mbps and up to 200m of Belden 1694A cable at 1.485 Gbps. The CYV15G0102EQ equalizer contains one power supply and typically consumes 160 mW power at 3.3V. The multi-rate equalizer is designed to meet the SMPTE 259M, SMPTE 292M, SMPTE 344M and DVB-ASI video standards. The equalizer meets all pathological requirements for SMPTE 292M as defined by RP198. and for SMPTE 259M as defined SDI, SDI CYV15G0102EQ accepts single-ended or differential serial video data streams over 75 coaxial cable. It is recommended to AC-couple the SDI, SDI inputs as they are internally biased to 1.2V. Document #: 001-04205 Rev. *A Page 3 of 10 PRELIMINARY SDO, SDO The CYV15G0102EQ has differential serial output interface drivers that use current mode logic [CML] drivers to provide source matching for the transmission line. These outputs can be either AC coupled or DC coupled to HOTLink II SerDes device. CYV15G0102EQ 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, the voltage at the CD/MUTE output will be greater than 3.0V. If CD/MUTE is used as an output, and the incoming data stream is present, then the voltage at the CD/MUTE output will be less than 0.8V. If CD/MUTE is used as an input, and tied to ground, the equalizer serial outputs are not muted and the MCLADJ setting is overwritten. If the CD/MUTE is used as an input and is tied to VCC, then the equalizer serial outputs are muted and the MCLADJ setting is overwritten. 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 and the MCLADJ setting is overwritten. CLI Cable Length Indicator (CLI) is an analog output that gives an output voltage proportional to the cable length being equalized. CLI gives an approximation of the length of cable at the differential serial inputs (SDI, SDI). CLI works at high definition (HD) data rates as well as standard definition (SD) data rates. The graph in Figure 2 illustrates the CLI output voltage at various Belden 1694A cable lengths. With an increase in cable length, CLI output voltage decreases. MCLADJ Maximum Cable Length Adjust (MCLADJ) sets the approximate maximum amount of cable to be equalized. When the maximum cable length set by MCLADJ is reached, the outputs are muted. MCLADJ works at SD as well HD data rates. If the MCLADJ voltage is greater than the CLI output voltage, the equalizer serial differential outputs (SDO, SDO) are muted. If the MCLADJ voltage is less than CLI voltage, then the equalizer's differential serial outputs (SDO, SDO) are not muted and the incoming data stream is equalized. The graph in Figure 1 illustrates the voltage needed at MCLADJ input, to equalize various Belden 1694A cable lengths for SD and HD data rates. The MCLADJ pin can be left unconnected in applications that do not require muting of the outputs. BYPASS The CYV15G0102EQ has a bypass mode that allows the user to bypass the equalizer's equalization and DC restoration functions. When the Bypass mode is tied to VCC, the signal presented at the equalizer's differential serial inputs (SDI, SDI) is routed to the equalizer's differential serial outputs (SDO, SDO) without performing equalization. When BYPASS is tied to GND, 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 A capacitor of 1 F should be placed between the AGC pins of the CYV15G0102EQ equalizer. CD/MUTE Carrier Detect/MUTE (CD/MUTE) is a bidirectional pin that provides an indication of the signal being present at the Document #: 001-04205 Rev. *A Page 4 of 10 PRELIMINARY Maximum Ratings Above which the useful life may be impaired.
