Clock and data management portfolio is expanded

19 April 2006 DSP, Micros & Memory

Expanding its portfolio of clock and data management solutions, ON Semiconductor has 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 two clock divider with CML outputs that accepts differential LVPECL, CML, or LVDS inputs. It has a maximum input clock frequency of 14 GHz typical, and jitter of 130 femto-seconds (fs) typical. At this extended speed, the NB7L32M represents a new performance standard for silicon germanium-based discrete clock and data management ICs. It operates at 2,5 V or 3,3 V.

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 >2,5 GHz, and jitter of 1 ps typical. Its open collector output structure makes communication possible between a signal source operating at a different voltage than the destination IC. It operates at 3,3 V.

The NB4N11S is a 1:2 clock distribution chip with LVDS outputs that accept differential LVPECL, LVCMOS, LVTTL, CML, or LVDS inputs. LVDS is a common interface for signalling in FPGAs and ASICs as an inexpensive differential option. This device has a maximum input clock frequency of >2,0 GHz, and jitter of 500 fs typical. It operates at 3,3 V.

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 >4 GHz typical, and jitter of 1 ps typical. It supports a 2,5 V supply.
