VS-705 Voltage Controlled SAW Oscillator (VCSO)
9Pages

Single Frequency VCSO > Description > The VS-705 is a Voltage Controlled SAW Oscillator that operates at the fundamental frequency of the internal SAW lter. The SAW lter is a high-Q Quartz device that enables the circuit to achieve low phase jitter performance over a wide operating temperature range. A divider circuit is deployed for output frequencies less than 491.52 MHz. The oscillator is housed in a hermetically sealed leadless surface mount package and o ered on tape and reel. It has a tri-state Output Select function that provides one of three conditions: Output Disable, Output Set, or Output Enable.

Functional Test: Allows use of standard power supply biasing con guration. Pull down resistors are used for LV-PECL outputs and are removed for LVDS outputs. Since the LVDS outputs are AC coupled, the output DC levels cannots be measured. Production Test: DC levels shown for VEE, OSelect, & Vc are for devices con gured for 3.3V operation. LV-PECL outputs are DC coupled to 50Ω test equipment. LVDS outputs are connected to a digital volt meter, then AC coupled to the test equipment. The digital volt meter allows for Mid Level & Swing measurements. LV-PECL to LV-PECL: For short transmission...
