| CYV270M0104EQ Adaptive Video Cable Equalizer Features Functional Description The CYV270M0104EQ is an adaptive video cable equalizer designed to equalize and restore signals received over 75 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 approximate 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.

Pin Descriptions - CYV270M0104EQ Adaptive Video Cable Equalizer Name 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. The BYPASS setting is ignored when MUTE is HIGH. Connecting CD to the MUTE pin enables automatic muting of the equalizer when the signal is lost. Do not leave an 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 set by MCLADJ is not exceeded, CD outputs a voltage less than 0.8V. When the incoming data stream is not present or maximum cable length set by MCLADJ is exceeded, CD outputs a voltage greater than 2.8V. Connecting CD to the MUTE pin enables automatic muting of the equalizer when the signal is lost. MCLADJ Analog Input Maximum Cable Length Adjust. The maximum cable length to equalize is set by the voltage applied to the MCLADJ input. When the maximum cable length set by MCLADJ is reached, the CD indicator deasserts. If MCLADJ functionality is not required, then this pin should be left floating or tied to ground to allow maximum equalized cable length. 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 performing equalization. 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 is set HIGH, the BYPASS setting is ignored and the serial outputs are muted. AGC, AGC SDO, SDO SDI, SDI Power VCC GND Center Pad Power Gnd - Power Supply for Device. Connect to +3.3V DC.

IO Characteristics Signal Description Document Number: 001-12875 Rev. ** Page 3 of 9 [+] Feedback CYV270M0104EQ Equalizer Operation The CYV270M0104EQ is an adaptive video cable equalizer that equalizes standard definition (SD) serial digital interface (SDI) video data streams. The CYV270M0104EQ equalizer is optimized to equalize up to 350m of Belden 1694A and Canare L-5CFB cable at 270 Mbps. The device contains one power supply and typically consumes 160 mW power at 3.3V. The adaptive equalizer meets the SMPTE 259M and DVB-ASI video standards. It meets all pathological requirements for SMPTE 259M as defined by RP178. The CYV270M0104EQ Video Cable Equalizer is auto adaptive from 143 Mbps to 360 Mbps. The CYV270M0104EQ equalizer has multiple variable gain 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 CYV270M0104EQ has DC restoration for compensating the DC content of the SMPTE pathological patterns. MUTE MUTE is an input pin that controls the muting of the equalizer's output. If MUTE is set LOW, then the equalizer serial outputs are not muted. If MUTE is set HIGH, then the equalizer serial outputs are muted. When MUTE is active, the BYPASS setting is also ignored. Connecting CD to MUTE enables automatic muting of the equalizer when the signal is lost. Do not leave the MUTE pin floating. Always drive it to a known state. Carrier Detect (CD) Carrier Detect is an active LOW output pin that indicates the presence of a valid incoming data signal. When the incoming data signal is present and maximum cable length does not exceed the length that is set by MCLADJ, CD outputs a voltage less than 0.8V. When the incoming data stream is not present or maximum cable length exceeds the length that is set by MCLADJ, CD outputs a voltage greater than 2.8V. Connecting CD to MUTE enables automatic muting of the equalizer when the signal is lost. SDI, SDI CYV270M0104EQ accepts single-ended or differential serial video data streams over 75 coaxial cable. It is recommended to AC couple the SDI and SDI inputs because they are internally biased to 1.2V. SDO, SDO The CYV270M0104EQ 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 HOTLink II receivers. BYPASS The CYV270M0104EQ has a bypass mode that enables the user to bypass the equalizer's equalization and DC restoration functions. 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 differential serial outputs (SDO, SDO). MCLADJ Maximum Cable Length Adjust (MCLADJ) sets the approximate maximum amount of cable to equalize. When the maximum cable length set by MCLADJ is reached, the CD pin deasserts. To enable automatic muting of the device when the signal is lost, tie CD directly to MUTE. The graph in Figure 2 on page 7 illustrates the voltage required at MCLADJ input to equalize various Belden 1694A cables. The same graph applies for Canare L-5CFB cables. If MCLADJ functionality is not required, this pin should be left floating or tied to ground to allow maximum equalized cable length. AGC Place a 1 F capacitor between the AGC and AGC pins of the CYV270M0104EQ equalizer.
