Epson Introduces High-Frequency Differential-Output PLL-Based Crystal Oscillators – Nov 14, 2013– Tokyo, Japan (Techreleased) – Seiko Epson Corporation today introduces a new family of small, accurate, high-frequency differential-output*1 PLL-based*2 crystal oscillators that support frequencies up to 700 MHz. In addition to the SG3225, whose tiny 3.2 mm x 2.5 mm footprint will enable electronics manufacturers to significantly reduce the size of assembled circuit boards, the product family also includes the SG5032 and SG7050, which come in popular sizes of 5.0 x 3.2 mm and 7.0 x 5.0 mm, respectively.
Networking, consumer, and industrial electronic systems must all handle higher data rates in less space, often without forced-air cooling. As a result, crystal devices must operate at higher frequencies with better accuracy and lower jitter and these devices must be smaller and operate over a wide temperature range. These needs cover a wide field of applications from consumer, networking, wireless base stations, blade servers*3, and the growing Internet of Things (IoT)
In order to meet these market demands, Epson combined its miniature quartz crystals with PLL ICs to develop this family of differential-output PLL-based crystal oscillators. With a frequency tolerance of +/-20 x 10-6 and low phase jitter of 270 femtoseconds*4, these oscillators offer outstanding accuracy and stability and have a wide operating temperature range (-40°C to +85°C). The SG3225, SG5032, and SG7050 are available in two popular output types, LV-PECL and LVDS.
