Each channel integrates a fully adaptive CTLE providing up to 34 dB of boost at 5 GHz, a 5-tap self-tuning DFE for post-cursor ISI cancellation, and a CDR for clock recovery and data re-timing. The transmitter includes programmable output voltage (600-1300 mVp-p) and de-emphasis (up to -15 dB) for pre-compensating downstream channel losses. At only 180 mW per channel, the device offers industry-leading power efficiency. The on-chip eye monitor and PRBS generator\/checker enable comprehensive link diagnostics during both development and deployment phases.","working_principle":"The DS125DF410 receives degraded serial data and processes it through a multi-stage signal conditioning pipeline. The adaptive CTLE analyzes the incoming signal spectrum and applies programmable high-frequency boost to compensate for the channel's low-pass characteristic. The adaptive algorithm continuously monitors the equalized signal quality (via eye monitor) and adjusts the CTLE settings in real-time. The equalized signal then enters the 5-tap DFE, which uses decisions from the previous five bits to cancel their post-cursor ISI contributions. The DFE coefficients are self-tuned using an LMS (Least Mean Squares) algorithm. The CDR uses a bang-bang phase detector and a low-jitter VCO to extract a clean clock from the equalized data, which is then used to re-time the retimed data at the output. The transmit FIR filter provides programmable pre-cursor and post-cursor emphasis to pre-compensate for the downstream channel, with the output swing and de-emphasis level set via SMBus registers or EEPROM.","pin_description":"<table><tr><th>Pin Group<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1-2<\/td><td>CH0_IN_N\/P<\/td><td>Input<\/td><td>Channel 0 CML input pair<\/td><\/tr><tr><td>3-4<\/td><td>CH0_OUT_N\/P<\/td><td>Output<\/td><td>Channel 0 CML output pair<\/td><\/tr><tr><td>5-8<\/td><td>CH1_IN\/OUT<\/td><td>I\/O<\/td><td>Channel 1 input\/output pairs<\/td><\/tr><tr><td>9-12<\/td><td>CH2_IN\/OUT<\/td><td>I\/O<\/td><td>Channel 2 input\/output pairs<\/td><\/tr><tr><td>13-16<\/td><td>CH3_IN\/OUT<\/td><td>I\/O<\/td><td>Channel 3 input\/output pairs<\/td><\/tr><tr><td>17-18<\/td><td>SCL\/SDA<\/td><td>I\/O<\/td><td>SMBus\/I2C control interface<\/td><\/tr><tr><td>19<\/td><td>INT_N<\/td><td>Output<\/td><td>Interrupt output (active low)<\/td><\/tr><tr><td>20<\/td><td>RESET_N<\/td><td>Input<\/td><td>Device reset (active low)<\/td><\/tr><tr><td>21-24<\/td><td>VDD_2.5<\/td><td>Power<\/td><td>2.5V supply pins<\/td><\/tr><tr><td>25-32<\/td><td>GND<\/td><td>Power<\/td><td>Ground<\/td><\/tr><tr><td>33-40<\/td><td>CH0-3_REF<\/td><td>I\/O<\/td><td>Channel reference \/ bypass pins<\/td><\/tr><tr><td>41-48<\/td><td>VDD\/GND\/NC<\/td><td>Power\/\u2014<\/td><td>Power, ground, no-connect<\/td><\/tr><tr><td>EP<\/td><td>Thermal Pad<\/td><td>Power<\/td><td>Exposed pad \u2014 connect to GND<\/td><\/tr><\/table>","application_scenarios":"<ul><li>10G-KR backplane retiming in data center top-of-rack switches with 34 dB channel loss<\/li><li>CPRI option 8 (9.8 Gbps) front-haul link conditioning in 5G C-RAN<\/li><li>40G-SR4 optical module retiming with four 10.3 Gbps channels<\/li><li>12G SAS signal integrity enhancement in enterprise JBOD enclosures<\/li><li>Interlaken 12.5 Gbps link extension across long backplane traces<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>DS125DF1610FB\/NOPB<\/td><td>FCBGA-196<\/td><td>16-channel version, same family<\/td><\/tr><tr><td>TI<\/td><td>DS160PR410<\/td><td>WQFN-48<\/td><td>4-ch 25.8G retimer, PCIe Gen4<\/td><\/tr><tr><td>Renesas<\/td><td>5P49V6965<\/td><td>QFN-72<\/td><td>8-channel retimer<\/td><\/tr><tr><td>Marvell<\/td><td>88X3310<\/td><td>BGA-324<\/td><td>KR retimer for 10G\/40G<\/td><\/tr><tr><td>MaxLinear<\/td><td>XR52810<\/td><td>QFN-48<\/td><td>4-channel 12.5G retimer<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10703","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/comments?post=10703"}],"version-history":[{"count":0,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/posts\/10703\/revisions"}],"wp:attachment":[{"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/media?parent=10703"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/categories?post=10703"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/tags?post=10703"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/ic-vendor.com\/es\/wp-json\/wp\/v2\/chip_brand?post=10703"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
