3.3V PECL/ECL DIFFERENTIAL

PHASE-FREQUENCY DETECTOR

Precision Edge

SY100EP140L

FEATURES

■ >2GHz maximum frequency

■ < 220ps rise/fall time

ECL Pro™

■ Low-voltage: +3.3V ±10% operation

DESCRIPTION

■ Wide operating temperature range: –40°C to +85°C

■ Fully differential throughput architecture

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.

■ Transfer gain:

1.0mV/degree at 1.4GHz

1.2mV/degree at 1.0GHz

■ Available in 8-Pin SOIC package

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.
