Hittite's New DC to 24 GHz Time Delay For 10G, 40G RZ-DQPSK & 100G DWDM RZ
March 6, 2012 Press Release
-- Ideal for Both Clock & Data Lane Alignment Applications
MA, 03/6/2012 - Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions for
communication & military markets, has recently expanded its Broadband Time Delay/Phase shifter portfolio adding
HMC911LC4B, which is ideal
for 10G, 40G RZ-DQPSK, 100G DWDM RZ Carver clock chain and skew adjustments in the fiber optic domain.
is a DC to 24 GHz Broadband Time Delay product that provides a continuously variable delay from 0 ps to 70 ps
while maintaining a constant differential output voltage swing. The device accepts either single-ended or
differential input data, while the differential output swing is adjustable from 150 mVp-p to 800 mVp-p. The
modulation bandwidth is 1.6 GHz, which is the highest phase modulation bandwidth available in the market. Suitable
for both clock and data retiming applications, the
features internal temperature compensation and bias circuitry to minimize delay variations with temperature. All
RF input and outputs of the
are internally terminated with 50 Ohms to Vcc, and may either be AC or DC coupled. Output pins can be connected
directly to a 50 Ohm to Vcc terminated system, while DC blocking capacitors must be used if the terminated system
input is 50 Ohms to a DC voltage other than Vcc.
also complements many of Hittite’s limiting amplifiers, modulator drivers and high speed logic products to provide
a complete solution for fiber optic and test equipment applications. The
is housed in a ceramic RoHS compliant 4 x 4 mm SMT package, and is fully specified for operation from -40 °C to
Samples 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

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
