It accepts a differential ECL data input and outputs a retimed differential ECL data stream with a recovered clock, all on a single 4.5 V to 5.5 V supply. The 1:2 input-to-output ratio means it can fan out the recovered clock to two destinations — useful for driving a line interface and a local framer simultaneously. ## ECL I/O — plan the logic interface Both input and output are ECL levels. That is the key interface constraint: the downstream receiver must accept ECL swings, or you need a level translator (e.g., to PECL or LVPECL) if your framer or FPGA bank runs on a different standard. The differential I/O path (Yes/Yes) gives common-mode rejection on the backplane — helpful in a telecom shelf where ground bounce between cards is a real concern. ## Industrial temperature range, active lifecycle Rated -40°C to 85°C, this part covers outdoor telecom cabinets and uncontrolled equipment rooms without a derating headache. The lifecycle status is Active, so there is no LTB or EOL clock ticking — it can be specified into new production builds and dual-sourced through independent distribution. ## 20-SOIC footprint — board layout note Housed in a 20-SOIC wide-body (7.50 mm width), surface-mount.","metaTitle":"AD80052BR Clock Recovery & Data Retiming IC, 51.84 MHz","metaDescription":"AD80052BR PLL-based clock recovery and data retiming IC for STS-1.
