VSC7718, VSC7728
GPON and GE-PON OLT Transimpedance Amplifier and Limiting Amplifier Chipset
VSC7728
VSC7718
F E AT U R E S :
Burst average received power monitor
Reset through the high-speed data interface
Fast settling time
Differential Data Ready (DATRDYP, DATRDYN) output
LVPECL outputs
Bare die or 16-pin 3 mm x 3 mm QFP package
BENEFITS:
Enables the system to monitor the burst power to determine if there are
any issues with the ONU transmission
Reduces pin count for the BOSA
Enables the receiver to meet GPON settling-time requirements
Used to latch the receive power monitor as well as tell the downstream
CDR when to start acquiring good data
Standard interface that directly couples to the CDR
Small enough to fit in a SFF or SFP module along with a laser driver to
achieve a complete solution
