SY89601L — 3.3V, 77.75MHz to 694MHz
Precision Frequency Synthesizer and Jitter
Attenuator with Ultra-Low Phase Noise
The SY89610L is a 3.3V, fully differential CML frequency synthesizer and
jitter attenuator that accepts a noisy clock between 19.44MHz and 694MHz,
depending on I/O frequency selection, and provides an ultra-low jitter clock
signal. This corresponds to an output clock frequency between 77.75MHz
and 694MHz covering SONET, SAS, SATA, Fibre Channel, and many other
standards. Output jitter is typically 1psrms. The SY89610L includes a 1kHz
to 10kHz programmable loop bandwidth so it can accommodate different
jitter attenuation applications and PLL requirements.
The SY89610L has an auto-tune circuit that enables precision frequency cal-
ibration. Auto-tuning is initiated on a LOW to HIGH transition on the RESET
input and during power-up. This feature requires a valid reference input.
The differential input includes Micrel’s unique, 3-pin input termination archi-
tecture that interfaces to LVPECL, LVDS or CML differential signals, (AC-
coupled or DC-coupled) as small as 100mV without any level-shifting or ter-
mination 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
50Ω loads, with rise/fall times guaranteed to be less than 250ps.
The SY89610L operates at 3.3V ±10% supply and the output can accom-
modate 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 SY89610L is part of Micrel’s Precision Edge
SY89297U — 2.5V, 3.2Gbps Precision CML
Dual-Channel Programmable Delay
The SY89297U is a DC-3.2Gbps programmable, two-channel delay line.
Each channel has a delay range from 2ns to 7ns (5ns delta delay) in pro-
grammable increments as small as 5ps. The delay step is extremely linear
and monotonic over the entire programming range, with 20ps INL over tem-
perature and voltage.
The delay varies in discrete steps based on a serial control word provided
by the 3-pin serial control (SDATA, SCLK, and SLOAD). The control word for
each channel is 10-bits. Both channels are programmed through a common
serial interface. For increased delay, multiple SY89297U delay lines can be
cascaded together.
The SY89297U provides two independent 3.2Gbps delay lines in an ultra-
small 24-pin (4mm x 4mm) MLF
consider the SY89295U and SY89296U single-channel delay lines. Evalua-
tion boards are available for all these parts.
