Application
The Connor-Winfield SCG2000 Series provides high precision phase lock loop frequency translation for the telecommunication applications. SCG2000 Series is well suited for use in line cards, service termination cards and similar functions to provide reliable reference, phase locked, synchronization and low phase gain for TDM, PDH, SONET and SDH network equipment. The SCG2000 Series provides a jitter filtered, wander following output signal synchronized to a superior Stratum or peer input reference signal.

General Description
The SCG2000 Series provides high precision phase lock loop frequency translation for the telecommunication applications. The SCG2000 products generate a CMOS output from an intrinsically low jitter, voltage controlled crystal oscillator. Most models provide a jitter attenuated, internal reference that is connected to a Reference Output pin. SCG2000 Series is well suited for use in line cards, service termination cards and similar functions to provide reliable reference, phase locked, synchronization for TDM, PDH, SONET and SDH network equipment . The SCG2000 Series provides a low phase gain (<0.2dB), jitter filtered, wander following output signal synchronized to a superior Stratum or peer input reference signal. The SCG2000 Series include the following features: Free Run, Tri-state and alarm outputs for Loss-of-Reference, (LOR), Loss-of-Lock, (LOL). During the LOR alarm, the SCG2000 will also enter a Free Run state which will guarantee a 20 ppm accurate output. Additionally the Free Run mode may be entered manually by asserting a high signal to the Free Run Enable pin. The outputs may be put into the tri-state high impedance condition for external testing purposes by asserting a high signal to the Tri-State Enable pin. The SCG2000 Series are 3.3 Volt components that typically draw less than 100 mA. All models have an acquisition time of approximately 1.0 second and can be used in applications that require temperature rating of 0 70 C. All models have a 33W resistor in series with the oscillator output. The SCG2000 package dimensions are .775" x .825" x .35" on a six layer FR4 board with surface mount pins. Parts are assembled using high temperature solder to withstand surface mount reflow process.

* Input References (Pin #8) at 19.44 MHz. * Oscillator Output (Pin #9) at 19.44 MHz. * Reference Output (Pin #1) at 8 kHz. The SCG2010 is designed as a clean-up PLL with the input reference frequency (Pin #8) equal to the oscillator output (Pin #9). The reference output frequency (Pin #1) is 8 kHz. The LOL alarm is designed to tolerate 1us pp of jitter on the reference. Jitter greater than 1us p-p will result in LOL alarm pulses.
