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. Designed to be used in conjunction with one another, the VSC7728 supplies a reset signal to the VSC7718 in order to control its internal offset correction circuitry, providing fast settling times with immunity to long streams of consecutive identical digits. The VSC7718 also features a space-saving filter connection provided for positive bias to a PIN diode through a filter resistor to VCC. The VSC7718 is available as bare die with padout optimized for standard 4-pin, 5-pin and 6-pin TO-46 packages. The VSC7728 is available in a 16-pin, 3mm x 3mm QFP package.
