VLML52151X is a 3.3V Voltage
Controlled Crystal Oscillator
(VCXO) with LVDS Differential
outputs. The VLML52151X is
designed with a 2X analog
frequency multiplier to achieve
higher frequencies with low
jitter and tight frequency
stability.

Inclusive of calibration @ 25°C, frequency stability vs. temperature, power supply variation, Aging over 15 years
and load variations. Control voltage (Vc) = 1.65 Vdc.
Suppressed fundamental frequency.
Absolute pull range (APR) is the minimum guaranteed pull range of the VCXO under all conditions over lifetime
operation. The APR is referenced to Fo. Positive slope.

When the oscillator is disabled, the outputs are at High Impedance. Output is enabled with no connection on pad 2.
Vod measured with 100 ohm resistor between the true output and the complementary output.
Specifications subject to change without notice.
