Overview
SINGLE CHANNEL 0.
7V DIFFERENTIALTO-LVTTL TRANSCEIVER ICS8512061I Features • • • • • • • • • One HCSL output pair and one LVCMOS/LVTTL output One single-ended LVCMOS/LVTTL signal input LVTTL I/O signal: up to 250MHz HCSL interface pins in high impedance state when the device is powered down Power-up and power-down glitch-free Additive Phase Jitter, RMS: 0.
23ps (typical) Full 3.
3V operating supply -40°C to 85°C ambient operating temperature Available in lead-free (RoHS 6) package General Description ICS HiPerClockS™ The ICS8512061I is a transceiver which can interchange data across multipoint data bus structures.
The device has an LVTTL driver and one HCSL receiver driver.
It translates between LVTTL signals and HCSL signals.
