SP5668
ELECTRICAL CHARACTERISTICS (continued)
T_AMB = 120°C to +80°C, V_CC = +4.5 to +5.5V. Reference frequency = 4MHz. These characteristics are guaranteed by either
production test or design. They apply within the specified ambient temperature and supply voltage ranges unless otherwise
stated.

* REF output should be connected to V_CC if unused
** Note: 1. -148dB @ 1KHz offset with 1MHz comparison frequency measured at the phase comparator.
2. When external reference is used, a high signal level is required for low phase noise.
