1 / 8 page ![]() General Description The MAX3634 burst-mode clock phase aligner (CPA) is designed specifically for 622Mbps or 1244Mbps GPON (ITU G.984) optical line terminal (OLT) receiver applica- tions. The MAX3634 provides clock and clock-aligned resynchronized upstream data through differential LVPECL outputs. Using the OLT system clock as a ref- erence, the MAX3634 aligns to the input data and acquires within the first 13 bits of the burst. The CPA operates with received data that is frequency locked to the OLT reference. The acquisition time, bit-error ratio, and jitter tolerance all support GPON PMD specifica- tions. LVPECL high-speed clock and data outputs pro- vide compatibility with FPGAs at 622Mbps and with the MAX3885 deserializer at 1244Mbps. The MAX3634 is available in a low-profile, 7mm x 7mm, 48-lead TQFN package. The MAX3634 operates from a single +3.3V supply, over the -40 °C to +85°C tempera- ture range.
