CFPV-7 Low Power Miniature SMD VCXO
ISSUE 4 - draft; 4 OCTOBER 2004
Delivery Options
■ Please contact our sales office for current leadtimes
Description
■ Voltage controlled crystal oscillator (VCXO) with crystal
packed into its own holder
■ Grounded crystal enclosure acts like a shield and
provides low EMI
■ Non PLL based design ensures low jitter
■ 3.3V or 5V supply voltage
■ CMOS, PECL, SINE or LVDS Output
RoHS Compliance
■ Parts with the suffix ‘LF’ on the part number are fully
comliant with the European Union directive 2002/95/EC
on the restriction of the use of certain hazardous
substances in electrical and electronic equipment.
Note: The RoHS compliant parts are suitable for
assembly using both Lead-free solders (see Lead-free
Reflow soldering profile) and Tin / Lead solders
(see Tin / Lead Reflow soldering profile)
Standard Frequencies
■ 8.192, 20.0, 24.576, 32.768, 34.368, 38.88, 39.3216,

■ VoL: <10% Vs
■ Tri-state control (6 pad package only)
Control Input Logic ‘0’ (< 30% Vs) will put the output in
the tri-state mode
Control Input Logic ‘1’ (> 70% Vs) or left unconnected
will enable the output
‘Active High’ is standard but a version with ‘Active Low’
can be supplied on request
Single Ended or Differential PECL Output (option)
■ Load: 50Ω to Vs-2V
■ _{Duty Cycle @ 50%: 40/60%}
■ Rise & Fall Time (20%-80%): < 0.5ns typ.
■ VoH: 2.4V typ. @Vs=3.3V
■ VoL: 1.5V typ. @Vs=3.3V
■ Tri-state control
The output is enabled if tri-state control is:-
a) Left open circuit
b) Connected to GND
c) Connected to a voltage <(Vs-1.65V) = PECL logic low
The output is disabled if tri-state control is:-
a) Connected to Vs
b) Connected to a voltage >(Vs-0.96V) = PECL logic high
When disabled, pad 5 goes low and pad 4 goes high.
The tri-state control pad has an internal 75kΩ pull down
to GND resistor
Sine Output (option)
■ Load: 50Ω
■ Level: can be specified up to +8dBm
■ Harmonics: < –20dBc
LVDS Output (option)
■ Load: 100Ω differential +10pF each output to GND
■ Diff. output voltage: ±250mV min. ±400mV max.
■ Duty Cycle @ 50%: 40/60%
■ Rise & Fall Time (20 to 80%): <0.5ns typ.
■ Tri-state control (6 pad package only)
Control Input Logic ‘0’ (0.8V) will put the output in
tri-state mode
Control Logic’1’ (>2.0V) will enable the output
Frequency Stability
■ All causes stability (including calibration, temperature,
supply, load, reflow and ageing) can be specified down
to ±30ppm, 0 to 70°C or ±50ppm, –40 to 85°C. Please
specify operating condition; Temperature Range,
Lifetime, etc.
