Hittite's New DC to 8 GHz Ultra Low Noise 1:9 Fanout Buffer
January 6, 2012 Press Release
-- Targeting Clock Distribution for ADC/DACs, Cellular Infrastructure, SONET, Fibre Channel, & GbE
MA, 01/06/2012 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets announces the release of
HMC987LP5E, a high
performance 1:9 Fanout Buffer which is ideal for low noise clock distribution in cellular infrastructure, SONET,
Fibre Channel, Gigabit Ethernet and ADC/DAC applications.
The HMC987LP5E features industry leading jitter
performance of 0.6 attoseconds/√Hz or 50 fs over its entire DC to 8 GHz operating frequency range. Its flexible
I/O interface supports AC or DC coupling, LVPECL, LVDS, CML, and is CMOS compatible. Completely configurable, the
HMC987LP5E features 8 differential or 16 single-ended LVPECL outputs, and one CML output with adjustable
swing/power level in 3 dB steps. Integrated parallel or serial control allows users to enable or disable
individual HMC987LP5E outputs to reduce power consumption when not needed. The HMC987LP5E is housed in plastic
leadless surface mount package and provides excellent temperature stability over the -40°C to 85°C temperature
Also released is the
, which replaces the
XOR/XNOR gate function. The HMC745LC3 is available in a ceramic RoHS compliant 3 x 3 mm SMT package and serves as
an alternate to Inphi's 13611XR, while supporting data transmission rates up to 13 Gbps, and clock rates up to 13
GHz. The differential CML inputs to the HMC745LC3 are terminated with 50 Ohms to the positive supply and bypassed
on-chip to a transmission line return signal at ground, and may be either AC or DC coupled. The differential
outputs may be either AC or DC coupled. Propagation delay is typically 95 ps, while rise and fall times are 21 and
19 ps respectively. The HMC745LC3 provides 2 ps of deterministic jitter and dissipates only 240 mW.
and evaluation PC boards for all SMT packaged products are available from stock and can be ordered via the
company’s e-commerce site or via direct purchase order. Released data sheets are available on-line at www.hittite.com.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling
2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas
and reference material while performing my work as an RF system and circuit design engineer.
The Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
