CYV15G0104EQ Multi Rate Video Cable Equalizer Features Functional Description ■ Multi rate adaptive equalization ■ Operates from 143 to 1485 Mbps serial data rate ■ SMPTE 292M, SMPTE 344M, and SMPTE 259M compliant ■ Supports DVB-ASI at 270 Mbps ■ Maximum cable length adjustment for HD-SDI and SD-SDI data rates 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. ■ Carrier detect and mute functionality for HD-SDI and SD-SDI data rates ■ Equalizer bypass mode ■ Seamless connection with HOTLink II™ family ■ Equalizes up to 350m of Belden 1694A and Canare L-5CFB coaxial cable at 270 Mbps ■ Typically equalizes up to 200m of Belden 1694A and Canare L-5CFB coaxial cable at 1.485 Gbps ■ Low power: 160 mW at 3.3V ■ Single 3.3V supply ■ 16-pin Quad Flat No Lead (QFN) package ■ 0.18 μm CMOS technology ■ Pb-free and RoHS compliant ■ Pin compatible to existing QFN equalizer devices ■ Uses Cypress CLEANLink™ technology 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.

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. VCC Power Power Supply for Device.

The CYV15G0104EQ 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 CYV15G0104EQ multi rate cable equalizer operates from 143 Mbps to 1.485 Gbps serial data rate. MUTE is an input pin that controls the muting of the equalizer’s output. MUTE operates for both HD and SD data rates. If MUTE is set LOW, the equalizer serial outputs are not muted. If MUTE is set HIGH, then the equalizer serial outputs are muted. When MUTE is active, BYPASS setting is also ignored. Connecting CD to MUTE pin enables automatic muting of the equalizer upon loss of signal. 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 that set by MCLADJ, CD outputs a voltage less than 0.8V. The CYV15G0104EQ equalizer has multiple variable gain equalization stages that reverse the attenuation 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 CYV15G0104EQ has DC restoration to compensate for the DC content of the SMPTE pathological patterns. 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. SDI, SDI Connecting CD to MUTE pin enables automatic muting of the equalizer upon loss of signal. CYV15G0104EQ 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. BYPASS SDO, SDO The CYV15G0104EQ 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. 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 CD pin is deasserted. To enable automatic muting of the device upon loss of signal, CD should be tied directly to MUTE. MCLADJ works at SD and HD data rates. The CYV15G0104EQ 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). AGC Place a capacitor of 1 μF between the AGC and AGC pins of the CYV15G0104EQ equalizer Figure 2 on page 7 illustrates the voltage required at MCLADJ input to equalize various Belden 1694A cable lengths. If MCLADJ functionality is not required, this pin should be left floating or tied to ground to enable maximum equalized cable length.
