Integrated Device Technology (IDT ) has unveiled a high-performance quad frequency MEMS oscillator with multiple synchronous outputs. These new oscillators offer configurable outputs in an industry-standard compatible package footprint, saving board area and bill-of-materials (BOM) cost in communication, networking, storage, industrial, and FPGA applications.
The IDT 4E series ±50 ppm 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 600 MHz, the new oscillators save board area, simplify the application circuit, and reduce BOM cost in any high-performance application requiring an LVDS or LVPECL frequency source. Additionally, 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. This enables the customer to reduce their BOM count, consolidate their inventory, and realize cost benefits.
“Our new CrystalFree MEMS oscillators eliminate the need for additional quartz crystals and bring tremendous value to our customers,” said Christian Kermarrec, vice president and general manager of the timing and synchronization division at IDT. “While the new 4E series provides simplicity and cost savings, we’ve also maintained backward compatibility with their existing socket footprints to ease the transition to these new devices.”
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 – offering the flexibility to use the innovative devices in a myriad of applications.
