MICROCHIP ZL40208LDF1

The ZL40208 is an LVPECL clock fanout buffer with six output clock drivers capable of operating at frequencies up to 750MHz. The device is designed to fan out low-jitter reference clocks for wireline or optical communications applications while adding minimal jitter to clock signals. An internal linear voltage regulator and bulk capacitors minimize additive jitter caused by power supply noise. The device operates from a 2.5V ±5% or 3.3V ±5% supply voltage over an operating temperature range of -40°C to +85°C.
