Hittite Releases New 13, 28 & 45 Gbps High Speed Logic Products in SMT!
Ideal for 40/100 GbE, 40G DQPSK, 100G DP-QPSK, 14G Fiber Channel & Infiniband EDR
MA, 09/3/2010 – Hittite Microwave Corporation, the world class supplier of complete MMIC based solutions
for communication & military markets has expanded its High Speed Logic product line with the release of four new
logic devices including a 28 Gbps 1:2 Fanout Buffer, a 13 Gbps 1:4 Fanout Buffer, and two XOR/XNOR gates operating
at 28 Gbps and 45 Gbps. These devices are ideal for a wide range of new and emerging optical, networking, and
storage area network (SAN) standards including: 40/100 GbE, 40G (D)QPSK ,100G DP-QPSK, 14G Fiber Channel and
Infiniband EDR, and broadband test equipment.
HMC850LC3C is a 1:2 Fanout Buffer designed to support data transmission rates up to 28 Gbps, and clock
frequencies as high as 20 GHz. The HMC940LC4B is Hittite’s first 1:4 Fanout Buffer, and supports data transmission
at up to 13 Gbps, or clock buffering up to 13 GHz. These Fanout Buffers feature differential inputs and outputs
which are DC coupled and terminated on chip with 50 Ohm resistors to ground. The outputs may be used in either
single-ended or differential modes, and should be AC or DC coupled into 50 Ohm resistors connected to ground. The
HMC850LC3C 1:2 Fanout Buffer exhibits propagation delays of 75 ps, while rise and fall times are less than 16
ps. Ideal for high performance, broadband test applications, the
HMC850LC3C exhibits only 2 ps p-p of deterministic jitter and less than 0.2 ps rms of additive random jitter.
HMC851LC3C and the
HMC844LC4B are XOR/XNOR gate functions which support clock frequencies as high as 28 GHz and data transmission
rates up to 28 Gbps and 45 Gbps respectively. All input signals to these XOR/XNOR gates are terminated with 50
Ohms to ground on-chip, and may be either AC or DC coupled. The differential outputs may be either AC or DC
coupled, and should be connected directly to a 50 Ohms-to-ground terminated system.
HMC851LC3C exhibits propagation delays of 97 ps, while rise and fall times are less than 15 ps. Deterministic
jitter is typically less than 2 ps p-p, while additive random jitter is less than 0.2 ps rms. For the
HMC844LC4B XOR/XNOR gate, typical propagation delay is 90 ps, while rise and fall times are less than 11 ps.
Deterministic jitter is less than 3 ps p-p, while additive random jitter is less than 0.2 ps rms.
devices operate from a single -3.3 V DC supply, and feature an output level control pin, which allows for loss
compensation or for signal level optimization.
HMC844LC4B complement many of Hittite’s previously released Fiber Optic and High Speed Logic products, are
housed in ceramic RoHS compliant SMT packages, and are specified for operation from -40 °C to +85 °C. Released
data sheets may be found at www.hittite.com. Samples and evaluation PC boards are available from stock and can be
ordered via the company’s e-commerce site or via direct purchase order.
