LVDS-Output High-Stability SAW Oscillators
-Q3805CA0xxxxx00 (EG-2121CA-L),
Q3806CA0xxxxx00 (EG-2102CA-L)- 

 

Singapore, 17 June 2003 – To support the need for increasingly fast high-speed serial communications, we have added a pair of LVDS output oscillators, the EG-2121CA-L (2.5 V operation) and the EG-2102CA-L (3.3V operation), to our existing line of well-received PECL output SAW oscillators, the Q3805CA (EG-2121CA-P) series (2.5V operation) and Q3806CA (EG-2102CA-P) series (3.3 V operation). In addition to LVDS output, the new oscillators feature higher duty cycle stability, facilitating circuit design. Both oscillators are currently available in production quantities.

*LVDS:

Low Voltage Differential Signaling. An interface for transmitting low-amplitude signals at low power consumption and high speeds. LVDS emits less electromagnetic interference (EMI) and consumes less power than other interface standards.
 

Features

  • LVDS output suited to high frequencies
  • High-stability SAW:
    50% improvement in thermal characteristics
  • High-stability duty cycle:
    ±2% (53.125 to 175 MHz, option)
  • Low jitter
  • Low-voltage operation
  • Completely lead-free product
  • Small package

Applications

  • Communications and other equipment using Serial-ATA, Fiber Channel, PCI-Express, Ethernet, Hyper-transport, IEEE1394b, or other high-speed serial communications.
