- Coupled with Epson’s VCXO, IDT’s New Clock Jitter Attenuator and FrequencySynthesizer Product Supports 40/100/400 Gbps Ethernet PHY and Other High-Performance Applications -
Seiko Epson Corporation (TSE: 6724, “Epson”), the world leader in Quartz crystal technology* and Integrated Device Technology, Inc. (IDT®) (NASDAQ: IDTI) today introduced an ultra-high performance timing solution addressing the phase noise challenges in telecommunication and data center applications. IDT’s new 8V19N474 jitter attenuator and frequency synthesizer is coupled with Epson’s VG-4513 high-performance voltage-controlled crystal oscillator (VCXO) to provide best-in-class phase noise performance for highly stringent applications, such as 40/100/400 Gbps Ethernet timing.
The new 8V19N474 jitter attenuator and frequency synthesizer boasts an ultra-low RMS phase noise of 75 femtoseconds; this level of performance hands the system designers the clocking requirement to transition from 28 Gbps to Ethernet interfaces using 56G PAM4 (TX) PHYs and other high-performance SerDes applications with ample timing margin.
IDT’s 8V19N474 generates up to 12 reference clock signals and outputs multiple high-performance synchronized clocks, making it ideal for Ethernet and OTN (OTU3, OTU4) in complex applications as well as driving ADC/DAC converters, cable TV head-end, and DOCSIS 3.1 applications. For wired communications, the solution enables compliance with physical layer specifications of phase noise, bit error rate, and signal-to-noise ratio without the need for external filtering. The integrated low drop out regulator lends a BOM savings by allowing the usage of an economical and inexpensive DC/DC voltage supply.
Epson’s VG-4513 VCXO is an essential and proven component in this solution. Using an HFF (high-frequency fundamental) crystal, Epson’s VG-4513 VCXO achieves very low close-in phase noise. The integrated VCO in IDT’s 8V19N474 provides exceptional phase noise at higher offset frequencies.
“IDT’s work with Epson underscores our commitment to delivering the timing technology needed for today’s most advanced designs,” said Kris Rausch, general manager of IDT’s Timing Products Division. “Our joint solution can be a significant help to engineers working on highest line rate Ethernet applications requiring best-in-class data transmission.”
“Epson is committed to developing network timing technology,” said Masayuki Kitamura, chief operating officer of Epson’s Microdevice Operations Division. “The very low phase noise of our VCXOs enables high-speed electrical interfaces, optical modules, and base stations. Our collaboration with IDT has created several reference designs serving a wide range of networking applications including Synchronous Ethernet, IEEE-1588, datacenter and carrier infrastructure, and RF converters for base stations.”
IDT’s 8V19N474 offers a wide output frequency range from 25 MHz to 2500 MHz, including 125 and 156.25MHz and LVDS and LVPECL outputs with adjustable amplitudes. IDT’s 8V19N474 is available now and comes in an 8 × 8 mm 81-CABGA package. Epson’s VG-4513 is available now and comes in a 7 mm × 5 mm × 1.6 mm or a 5 mm × 3.2 mm × 1.3 mm ceramic package.
