Key Attributes of the ASG Series
Configurable: ASG Series is based on a custom Integrated Circuit that is
configurable to provide the following features:
� XO or VCXO
� LVCMOS or LVDS or LVPECL Output
� +2.5V or +3.3V Supply Voltage
� Frequency Range: 10MHz to 250MHz for LVCMOS
� Frequency Range: 10MHz to 1.50GHz for LVDS & LVPECL
� Lower Power Consumption than competition
Phase Noise: Good Phase Noise, -118dBc/Hz typical at 1MHz offset; from
1.50GHz carrier
rms Jitter: Typical < 1.0 ps rms jitter over 12kHz to 20MHz Bandwidth
(@1.50GHz carrier with 1.60 ps rms Maximum)

Key Attributes of the ASG Series?
Power Consumption: < 60mA maximum with LVPECL output (25% less than competition)
Overall Stability: < ±50 ppm All Inclusive Frequency Stability over 10-year Product Life
(Inclusive of set-tolerance, reflow, frequency pulling and pushing &
Aging)
Size: Small form factor, 5.0 * 7.00 * 1.9 mm SMT Reflow-able package
Rise & Fall Time: Ultra fast, 350ps max. with LVPECL
Symmetry: 45% / 55% worst case

Typical Phase Noise Performance @ 1.50GHz Carrier
ASG series is designed to provide optimal jitter performance at high carrier
frequencies. Typical jitter of <1ps rms over 12kHz ~ 20MHz BW @ 1.5GHz
carrier is realized; with maximum guaranteed jitter of 1.6ps rms

The Quartz Crystal used inside the ASG series typically holds < ±15 ppm frequency
stability over the operating temperature range of -40ºC to +85ºC . The default
maximum F vs. T specification is < ±35 ppm; but it is possible to offer < ±25 ppm
@ a premium

The ASG series has a guaranteed ±50 ppm Minimum frequency pull over Vc = 0 ~ 3.3V.
This is sufficient pull to compensate for All Inclusive drift over 10-year Product Life
