DESCRIPTION
The Model 335 is a ceramic packaged Voltage
Controlled oscillator offering reduced size and
enhanced stability. The small size means it is
perfect for any application. The enhanced
stability means it is the perfect choice for today’s
communications applications that require tight
frequency control.
ORDERING INFORMATION
335
M
P = PECL, Enable High (standard)
L = LVDS, Enable High (standard)
E = PECL, Enable Low
V = LVDS, Enable Low
OUTPUT TYPE FREQUENCY IN MHz
M - indicates MHz and decimal point.
Frequency is recorded with minimum 4
significant digits to the right of the "M".
FREQUENCY STABILITY and APR SUPPLY VOLTAGE
5 = ± 25 ppm / ± 100 APR (3.3V only)
3 = ± 50 ppm / ± 50 APR (standard)
2 = ± 25 ppm / ± 50 APR
Example Part Number: 335P3C3155M5200
2 = 2.5 Vdc
3 = 3.3 Vdc
OPERATING TEMPERATURE RA NGE
C = 0°C to +70°C (standard)
I = -40°C to +85°C
