DESCRIPTION
■>2GHz maximum frequency
■< 220ps rise/fall time
■Low-voltage: +3.3V ±10% operation
■Wide operating temperature range: –40°C to +85°C
■Fully differential throughput architecture
■Transfer gain:
1.0mV/degree at 1.4GHz
1.2mV/degree at 1.0GHz
■Available in 8-Pin SOIC package
The SY100EP140L is a high-speed, 2GHz phase-
frequency detector optimized to control ultra-low noise
VCXOs (voltage-controlled crystal oscillators) in telecom and
datacom systems. The phase-frequency detector compares
two input signals—a reference input and a feedback input.
Any mismatches in the two input signal’s phase or frequency
will result in the output UP or DOWN pulse stream. When
the difference between the UP and DOWN outputs are
integrated, the resulting control signal speeds-up or slows-
down a VCO or acts as the error voltage for a precision
VCXO.
The SY100EP140L I/O is 100K LVECL/LVPECL
compatible. The device operates from a +3.0V to +3.6V
(LVPECL) or –3.0V to -3.6V (LVECL) supply voltage. The
output swing is 400mV with < 220ps rise/fall times, which
enables the part to operate at a very high frequency.
Operating temperature range is guaranteed over the –40°C
to +85°C industrial range.
