19-3818; Rev 0; 9/05 EVALUATION KIT AVAILABLE 622Mbps/1244Mbps Burst-Mode Clock Phase Aligner for GPON OLT Applications MAX3634 General Description Features The MAX3634 burst-mode clock phase aligner (CPA) is DC-Coupled Clock Phase Aligner for Burst-Mode designed specifically for 622Mbps or 1244Mbps GPON(ITU G.984) optical line terminal (OLT) receiver applica- GPON Applications tions. The MAX3634 provides clock and clock-aligned 13-Bit Burst Acquisition Time resynchronized upstream data through differentialLVPECL outputs. Using the OLT system clock as a ref- 0.85UI High-Frequency Jitter Tolerance erence, the MAX3634 aligns to the input data andacquires within the first 13 bits of the burst. The CPA Continuous Clock Output operates with received data that is frequency locked to Byte Rate (1/8th Data Rate) Reference Clock Input the OLT reference. The acquisition time, bit-error ratio,and jitter tolerance all support GPON PMD specifica- Lock Detect Output tions. LVPECL high-speed clock and data outputs pro-vide compatibility with FPGAs at 622Mbps and with the LVPECL Serial Data Input and Output MAX3885 deserializer at 1244Mbps. LVPECL Reset Input The MAX3634 is available in a low-profile, 7mm x 7mm,48-lead TQFN package. The MAX3634 operates from asingle +3.3V supply, over the -40°C to +85°C tempera- Ordering Information ture range.
