MEMS oscillators have multiple synchronous outputs
Integrated Device Technology is offering quad frequency MEMS oscillators with multiple synchronous outputs.
The IDT 4E series ±50ppm enhanced MEMS oscillators integrate an LVDS or LVPECL output with a synchronous CMOS output into a single package, eliminating the need for an external crystal or secondary oscillator.
Available in frequencies up to 600MHz, the oscillators feature two control pins to select between four factory-programmable output frequencies, allowing for the replacement of four components with a single device.
The IDT 4E series oscillators are designed with the physical dimensions and pinout of an industry-standard six-pin CMOS, LVDS or LVPECL oscillator, but with four additional pins (10 pins total) strategically placed to maintain backward compatibility with existing six-pin sockets.
This allows designers to use the oscillators in existing sockets while offering additional functionality for new designs.
System designers can choose from three different output combinations: LVDS and CMOS outputs, LVPECL and CMOS outputs, or three synchronous CMOS outputs.chips, IDT, MEMS
