Integrated Device Technology Inc. (IDT) has unleashed a line-up of jitter attenuator and frequency synthesizer devices that boast ultra-high performance meeting the phase noise requirements of the most stringent applications such as JESD204B-compliant RF timing. The 8V19N407 and 8V19N408 support up to 3GHz output frequencies, as well as 82 femtoseconds of RMS phase noise, addressing the requirements of multi-carrier GSM radio transceivers as well as 40Gb and 100Gb Ethernet PHYs and other high-performance applications, detailed the company.

The 8V19N407 and 8V19N408 generate clock and SYSREF signals for JESD204B subclass 1-compliant ADC/DAC converters in wireless, industrial and radar applications. These devices output multiple high-performance synchronised clocks that are geared for high-speed Ethernet and cable TV head-end applications.

For wireless communications, the devices enable compliance with GSM phase noise and blocker specifications without external filters. For 40/100GbE PHYs, the 8V19N407 and 8V19N408 generate low phase-noise clocks that reduce bit error rates and achieve reliable transmission.

The devices offer a wide output frequency range from 25MHz to 3000MHz and LVDS and LVPECL outputs with adjustable amplitudes. The 8V19N407 supports Ethernet frequencies, making it suitable for timing 40G and 100G Ethernet PHYs while the 8V19N408 includes dual voltage-controlled oscillators (VCOs) offering frequency plan flexibility.

The 8V19N407 and 8V19N408 jitter attenuator and frequency synthesiser products are available. They come in a 10mm x 10mm 72-VFQFN package.
