VSC7965

PON Integrated 155 Mbps to 1.25 Gbps Burst-mode Laser Driver and Limiting Amplifier

A P P L I C A T I O N S :

BPON, GE-PON, GPON burst-mode laser driver

S P E C I F I C A T I O N S :

Package size: 5 mm x 5 mm QFN

VSC7965

Maximum modulation = 80 mA

Typical core power = 330 mW

Operating temperature range = -40 °C to 100 °C

F E A T U R E S :

B E N E F I T S :

APC loop requires no initialization phase

Laser driver is ready to transmit upon power up

Allows the VSC7965 to be used in both PON and SFP module

VSC7965 meets the specification for BPON, GE-PON, and GPON

solutions

Allows PON module to interoperate with multiple upstream devices

Burst enable input supports LVPECL, LVDS, and LVTTL output levels

Selectable resistance on monitor diode input

Laser driver crossing point control

Improves accuracy of the monitor diode input by allowing the user to

select the resistance and capacitance in the input

Enables the user to adjust the level of the crossing point on the laser

driver output

Built-in eye safety support

No external components are required to meet IEC-60825 eye safety

specifications
