The equalizer is designed to meet SMPTE 259M data rates and is optimized for performance at 270 Mbps. The CYV270M0101EQ is optimized to equalize up to 350m of Belden 1694A coaxial cable at 270 Mbps. The CYV270M0101EQ connects seamlessly to the HOTLink II family of transceiver devices and HOTLink(R) receiver devices. The CYV270M0101EQ 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 SD-SDI data rates. The Maximum cable length adjust (MCLADJ) sets the approximate maximum cable length to be equalized. The CYV270M0101EQ’s differential serial outputs (SDO, SDO) mute, when the approximate cable length set by MCLADJ is reached.

CD/MUTE LVTTL I/O 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 2.9V.

BYPASS LVTTL Input 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.

GND Gnd Connect to Ground. Power Equalizer Operation The CYV270M0101EQ is an adaptive video cable equalizer designed to equalize standard definition (SD) serial digital interface (SDI) video data streams. The CYV270M0101EQ equalizer is optimized to equalize up to 350m of Belden 1694A cable at 270 Mbps. The CYV270M0101EQ equalizer contains one power supply and typically consumes 160 mW power at 3.3V. The adaptive equalizer is designed to meet the SMPTE 259M and DVB-ASI video standards. The equalizer meets all pathological requirements for SMPTE 259M as defined by RP178. The CYV270M0101EQ Video Cable Equalizer is auto-adaptive from 143 Mbps to 360 Mbps. Document #: 001-06830 Rev. *A The CYV270M0101EQ 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 eye. The CYV270M0101EQ has DC restoration for compensating the DC content of the SMPTE pathological patterns. SDI, SDI The CYV270M0101EQ accepts single-ended or differential serial video data streams over 75Ω coaxial cable. It is recommended to AC-couple the SDI, SDI inputs as they are internally biased to 1.2V. Page 3 of 10 [+] Feedback CYV270M0101EQ SDO, SDO equalizer’s input, or it controls the muting of the equalizer’s output. The CYV270M0101EQ 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 the HOTLink II SerDes device. 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 2.9V. 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. CLI 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. 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 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. 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 data rates. The MCLADJ pin can be left unconnected in applications that do not require muting of the outputs. CD/MUTE When an invalid signal or a signal transmitted with a launch amplitude of less than 500mV at SD data-rates is received, the equalizer’s serial outputs are muted and the MCLADJ setting is overwritten. BYPASS The CYV270M0101EQ 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 µF should be placed between the AGC± pins of the CYV270M0101EQ equalizer.
