General Description
The SY89610L is a 3.3V, fully differential jitter attenuator
and frequency synthesizer that accepts a noise clock
between 19.44MHz and 694MHz, depending on I/O
frequency selection. The output provides an ultra-low
jitter clock frequency between 77.75MHz and 694MHz
covering SONET/SDH, Gigabit Ethernet, Fibre Channel,
SAS, SATA, and many other communication standards.
The output jitter of the SY89610L is typically 1psRMS. It
has a 1kHz to 10kHz programmable loop bandwidth to
accommodate different jitter attenuation applications
and PLL requirements. The auto-tune circuit enables
precision frequency calibration.
The differential input includes Micrel’s unique, 3-pin
input termination architecture that interfaces to LVPECL,
LVDS or CML differential signals, (AC- 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 SY89610L operates at 3.3V ±10% supply and the
output can accommodate 1.8V to 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 SY89610L is part of Micrel’s
Precision Edge
product line.
