GENERAL DESCRIPTION :

The VSC7718 transimpedance amplifier (TIA) and VSC7728 post amplifier together form a complete chipset solution for Gigabit-capable Passive Optical Networks (GPON) and Gigabit Ethernet Passive Optical Networks (GE-PON) OLT burst-mode receivers. This chipset exceeds GPON requirements with better than –33 dBm sensitivity, industry-leading overload performance of better than –4 dBm and over 23 dBm of dynamic range.

FEATURES :

► 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

APPLICATIONS :

► GPON - G.984 1244 Mbps upstream, class A, B, B+, and C

► GE-PON - IEEE Std. 802.3ah (EFM),

1000BASE-PX10/20-U (GE-PON OLT)
