ON Semiconductor Expands Clock and Data Management Portfolio to Include New CML, LVDS and ECL Interfaces.

PHOENIX -- The new functions and increased performance levels of the expanded clock and data management portfolio offer increased flexibility for high-performance applications

Expanding its high-performance portfolio of clock and data management solutions, ON Semiconductor (Nasdaq: ONNN) today introduced the NB7L32M, NB4N11M, NB4N11S and NB4L52 -- highly accurate, fully differential interface ICs. The devices are designed for telecommunications, networking, high-end computing, and automated test equipment applications.

The NB7L32M is a divide by 2 Clock Divider with CML outputs that accepts differential LVPECL, CML, or LVDS inputs. With a maximum input clock frequency of 14 gigahertz (GHz) typical, and jitter of 130 femto-seconds (fs) typical, NB7L32M provides exceptional accuracy and speed for timing control applications. At this extended speed, the NB7L32M represents a new performance standard for Silicon Germanium-based discrete clock and data management ICs. The device operates at Vcc of 2.5 volts (V) or 3.3 V, includes 50 ohm input termination resistors and is packaged in a space-efficient, Pb-free, 3 mm x 3 mm QFN-16. NB7L32MMNR2G is priced at $27.00 per unit in 3,000-unit quantities.

The NB4N11M is a 1:2 Clock Distribution chip with CML outputs, which accepts differential LVPECL, LVCMOS, LVTTL, CML, or LVDS inputs. NB4N11M has a maximum input clock frequency of greater than 2.5 GHz, and jitter of 1 picosecond (ps) typical. It features an innovative open collector CML output that facilitates a high-speed interface between mixed voltage level ICs (1.8 V, 2.5 V and 3.3 V). This open collector output structure makes communication possible between a signal source operating at a different voltage than the destination IC. As Field Programmable Gate Arrays (FPGAs) and Application Specific ICs (ASICs) drive down toward lower voltage operation, the alternative to this device is usually level shifting using discrete components which add propagation delay, consume board space and increase costs. The NB4N11M requires no translation or level shifting. The device operates at Vcc of 3.3 V, and is packaged in a Pb-free 3 mm x 3 mm TSSOP-8. NB4N11MDTR2G is priced at $4.13 per unit in 2,500-unit quantities.

The NB4N11S is a 1:2 Clock Distribution chip with LVDS outputs that accept differential LVPECL, LVCMOS, LVTTL, CML, or LVDS inputs. Its introduction expands ON Semiconductor's industry-leading family of high-performance LVDS interface devices. LVDS is a common interface for signaling in FPGAs and ASICs as an inexpensive differential option. However, traditional CMOS-based LVDS devices lack the speed and precision necessary to delivery low jitter, tight timing signals. By marrying ON Semiconductor's cutting-edge bipolar capability with an LVDS compatible output structure, these LVDS devices offer better compatibility with mainstream ICs without sacrificing performance. This device has a maximum input clock frequency of greater than 2.0 GHz, and jitter of 500 fs typical. The device operates at Vcc of 3.3 V, and is packaged in a Pb-free QFN-16. NB4N11SMNR2G is priced at $3.50 per unit in 3,000-unit quantities.

The NB4L52 is a D Flip-Flop with LVPECL outputs, which accepts differential LVPECL, LVCMOS, LVTTL, CML, or LVDS inputs. NB4L52 has a maximum input clock frequency of greater than 4 GHz typical, and jitter of 1 ps typical. The NB4L52 is a pin-for-pin upgrade of the MC100EP52, adding support for a 2.5 V supply. The reduced voltage results in lower power consumption and the elimination of a power supply rail if it is otherwise unused. The device includes 50 ohm termination resistors, and is packaged in a Pb-free QFN-16. NB4L52MNR2G is priced at $5.00 per unit in 3,000-unit quantities.
