JUNE 16, 2010 -- Hittite Microwave Corp., a supplier of MMIC-based solutions for communication and military markets, has launched three logic devices which support 43-45 Gbps data transmission and clock rates up to 43 GHz.

These devices support many new and emerging optical, networking, and storage area network (SAN) standards, including: 100 GbE, 40G (D)QPSK, and 100G DP-QPSK.

The HMC841LC4B is a D-Type Flip-Flop which supports single-ended or differential operation, and data transmission rates up to 43 Gbps. The device operates with clock signals up to 43 GHz, and the input is broadband from DC to 43 GHz. During normal operation, data is transferred to the outputs on the positive edge of the clock; reversing the clock inputs accommodates negative-edge triggered applications.

The HMC842LC4B is a 1:2 Fanout Buffer designed to support data transmission rates up to 45 Gbps, and clock signals up to 28 GHz. The HMC843LC4B is configured to provide AND/NAND/OR/NOR functions supporting data transmission rates up to 45 Gbps, and clock frequencies as high as 25 GHz. The differential input and output signals of the HMC841LC4B, HMC842LC4B and the HMC843LC4B are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled.

The HMC841LC4B, HMC842LC4B and the HMC843LC4B exhibit only 2 ps p-p of deterministic jitter, and less than 300 fs of additive random jitter. For signal loss compensation or signal level optimization, an output level control pin permits the differential output voltage swing to be adjusted.
