High speed analog PCB techniques should be used. Location of system oscillators is critical, as close proximity to switching power supplies and surrounding logic can induce noise that is within the loop bandwidth of the oscillator. When using a single ended output, the unused output must be terminated. 1- Control Voltage 2- Analog Ground 3- Analog Vcc 4- Digital Ground 5- Clock Output 6- Complementary Output 7- Digital Ground 8- Digital Vcc 9- Digital Ground 10- Factory Test * FT IN FO RM AT IO N The high speed clock outputs of the GV94341B are bandwidth limited outputs which appear as a sine wave. Bandwidth limiting on the outputs minimizes higher frequency components as a result of fast rise and fall times. These clock outputs drive a 50 ohm transmission line environment. Careful layout of these signals is critical. 10 FUNCTIONAL BLOCK DIAGRAM PR O DU CT PR O DU CT High speed outputs are derived from an internal GaAs PhaseLocked Loop which is synchronized to a very low jitter VCXO. 1 IN FO RM AT IO N IN FO RM AT IO N PR O DU CT The GV94341B is a 2.48832 GHz Voltage Controlled Crystal Oscillator (VCXO) for use in OC-48 / STS-48 / STM-16 system applications. Powered by a single 3.3 Vdc power supply, the GV94341B consumes minimal power.
