EPSON LAUNCHES VCXOs FOR MOBILE BASE STATIONS AND OPTICAL COMMUNICATIONS EQUIPMENT
A product from the new VG-4513CB VCXO series
SAN JOSE, CA - March 11, 2013 -
Epson Electronics America (EEA) today announced that is has begun shipping samples of the VG-4513CB series of voltage controlled crystal oscillators (VCXO) Designed for optical networking and LTE (long-term evolution) base stations application, the VG-451
3CB uses a high-frequency fundamental
crystal to achieve output frequencies up to 500 MHz with no spurs and very low phase noise and low jitter
. The VG-4513CB is packaged in a very small package, 87% smaller than existing VCXOs, and has excellent vibration sensitvity.
Epson's VG-4513CB is the industry's first VCXO to deliver output frequencies up to 500 MHz without using a PLL or frequency multiplier. By using a high-frequency fundamental-mode AT-cut crystal, Epson achieves better realiability, lower poer, and lo
wer phase noise than existing 500 MHz VCXO products. Using a fundamental-mode crystal, Epson's VG-4513CB achieves very low jitter, 50 fs rms at 491.51 MHz. Unlike PLLs and frequency multipliers, Epson's fundamental technology does not generate spurs.
