Voltage Controlled Crystal Oscillators

3GPF576 Series +3.3V, “F” family, PECL Outputs

V C X O

MERCURY

Since 1973

3GPF576 VCXO products feature 0.4 ps typical phase jitter and

low phase noise (-132 dBc at 10 KHz for 155.520 MHz).

Differential PECL Outputs meet the requirements for

SONET, XDSL and other communication protocols.

vs Operating Temperature

Range

If custom, use “temperature range code + desired ppm stability” for the

stability code. Example: “C20” (±20 ppm over -10 to +70°C) or “I35”.

vs Supply Voltage Change ±3 ppm max.with ±10% supply voltage change

vs Load Change ±2 ppm max.with ±10% Load change:

Supply Voltage V_CC

+3.3 V ± 10 %

Output Voltage HIGH “1”, V_OH

Output Voltage LOW “0”, V_OL

2.275 V min.; 2.420 V max. Condition: 50 ohms to V_DD-2V

1.490 V min..; 1.680 V max. Condition: 50 ohms to V_DD-2V

38 MHz≤ fout ≤ 100 MHz: 70 mA max.

100 MHz< fout ≤ 320 MHz: 85 mA max

320 MHz< fout ≤ 640 MHz: 95 mA max

50 ohms into V_CC-2V or Thevenin equivalent (terminating resistors

required on all outputs). See test circuit below.

fout < 150 MHz: 0.5 ns typical; 0.7 ns max.

Current Consumption

320 MHz < fout ≤ 640 MHz: 0.3 ns. typical; 0.45 ns. max

Measured at 20% ↔ 80% of the wave form.

Duty Cycle

50% ± 5% max. measured at 50% waveform.

+1.65 V

Control Voltage Center

Control Voltage Range

Vcon= +0.3 V to +3.0 V

From ± 80 ppm to ± 120 ppm. Use “N” (minimum), “M”

Frequency Deviation Range

(maximum), “T” (typical, ±20%) for the desired range.

Example: 120M represents ±120 ppm maximum.

Linearity

6% typical; 10% max.

Slope Polarity (Transfer Function) Positive: Positive voltage for positive frequency shift
