General Description
The SY89482L is a 3.3V, fully differential CML jitter
attenuator that accepts a noisy clock between 622MHz
and 694MHz, and provides an ultra-low jitter of the input
clock signal. Output jitter is typically 1psRMS. The
SY89482L includes a 1kHz to 10kHz programmable
loop bandwidth so it can accommodate different jitter
attenuation applications and PLL requirements.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that interfaces to LVPECL,
LVDS or CML differential signals, (AC-coupled or DC-
coupled) as small as 100mV without any level-shifting or
termination resistor networks in the signal path. For AC-
coupled input interface applications, an on-board output
reference voltage (VREF-AC) is provided to bias the VT pin.
The outputs are compatible with 400mV typical swing
into 50
loads, with rise/fall times guaranteed to be less
than 250ps
The SY89482L operates at 3.3V ±10% supply and the
output can accommodate 1.8V-3.3V operation with the
dedicated output supply. The part is guaranteed to
operate over the full industrial temperature range
(–40°C to +85°C). The SY89482L is part of Micrel’s
Precision Edge
product line.
