The 12-channel ADCLK954 LVPECL and the ADCLK854 LVDS/CMOS clock-fanout buffers provide 75- and 100-fsec jitter, respectively. The clock buffers have a 9-psec skew, suiting use in high-speed ADCs and DACs, wireless-infrastructure equipment, medical-imaging applications, and industrial applications. The 4.8-GHz ADCLK954 has two selectable differential inputs using the input-select control pin. Both inputs have 100Ω on-chip termination resistors. The clock buffers operation over a –40 to +85°C temperature range. The ADCLK954 comes in a lead LFCSP-48 with 12 or 24 channels and costs $5.95 (1000); the ADCLK954 comes in a lead LFCSP-40 package with 12 channels and costs $6.95 (1000).
