CARDINAL COMPONENTS, INC.
CJAL/ CJAE 10MHz - 250MHz
Description
The Cardinal Cappuccino crystal oscillator is based on a high performance integrated circuit designed for use
in Cardinal’s continued expanding leadership products in the programmable frequency control industry.
Cardinal’s new Cappuccino design is today state of the art in oscillators. The Cappuccino line product features
10MHz to 1.5GHz with CJAL/ CJAE ranging 10MHz to 250MHz Output, 2.5V or 3.3V Supply Voltage,
LVDS/ LVPECL commercial -20°C to +70ºC and industrial temperature range -40°C to +85ºC.
Cardinal’s new CJAL/ CJAE series is competitively priced and has the lowest typical power consumption
23/54mA LVDS/ LVPECL (70% less power than the Fox XpressO™ oscillator), lowest jitter and best phase
noise over 10kHz to 20MHz vs. the traditional fixed frequency quartz oscillators and Surface Acoustic Wave
oscillators. Cardinal’s programming centers utilize modern robotics, for testing, programming and 100% final
testing as we do with all our programmable offerings. The Cardinal CJAL/ CJAE series line is offered in both
ceramic and low cost plastic industry standard packages.
Cardinal’s Cappuccino line fits in all applications requiring a reference frequency including Multimedia,
Computing, Networking, consumer etc.

OE Turn-on and Turn-off Times
Notes:
•
These measurements were all performed with an AC coupled output so that leakage currents do not affect
the timing of the measurement. This results in all outputs floating to the midpoint of the signal levels when
off.
•
When LVDS is disabled the output goes to the common mode voltage (approximately 1.25V).
•
When LVPECL is disabled the output goes to tri-state level which floats to Vol.
