Notes:
1. For best jitter and phase noise performance, always choose the smallest Kv that meets
the application’s minimum APR requirements. Lower Kv options minimize noise
coupling and jitter in real-world PLL designs. See AN266 for more information.
2. APR is the ability of a VCXO to track a signal over the product lifetime. A VCXO with an
APR of ±100 ppm is able to lock to a clock with a ±100 ppm stability over 15 years over
all operating conditions.

4. Minimum APR values noted above include worst case values for all parameters.
Example Part Number: 595AE148M500DGR is a 5 x 7 mm VCXO in a 6 pad package. The nominal frequency is 148.5 MHz, with a 3.3 V supply,
LVPECL output, and Output Enable active high polarity. Temperature stability is specified as ±20 ppm and the tuning slope is 95 ppm/V. The part is
specified for a –40 to +85 C° ambient temperature range operation and is shipped in tape and reel format.
Frequency(e.g., 148M500 is 148.5 MHz)
Available frequency range is 10 to 810 MHz. The position of “M” shifts
to denote higher or lower frequencies. If the frequency of interest
requires greater than 6 digit resolution, a six digit code will be
assigned for the specific frequency.
