Maxim Integrated Products rolled out what it touts as the industry's first burst-mode clock-phase aligner (CPA) for BPON and GPON applications. Operating at 622Mbps and at 1.244Gbps within the signal's first 13 bits, the new MAX3634 CPA can be DC-coupled to the optical line terminations (OLT) limiting amplifier. The device then takes the upstream burst data from the limiting amplifier and provides a clock and clock-aligned resynchronized, differential output. Using the OLT system clock as a reference at 1/8th the data rate, the MAX3634 aligns to the input data and is guaranteed to acquire a signal within the first 13 bits of the burst.

The new CPA has a high-frequency jitter tolerance of >0.8UI. It provides continuous high-speed LVPECL clock and data outputs that meet all PMD level GPON specifications, and are compatible with standard FPGAs. The MAX3634 also features a LVPECL reset input and a lock-detect output.

Rated for operation between the extended temperature range of -40°C to 85°C, the MAX3634 is available in a 7-by-7mm, 48-pin TQFN package, and has a suggested resale price of $15 (1,000-up, FOB USA). Evaluation kits are also available.
