The 8T73S208B-01NLGI is a high-performance differential LVPECL clock divider and fan-out buffer. This device is designed for frequency division and signal fan-out of high-frequency, low-phase noise clocks. The following are its core features:
A differential input reference clock
The differential pair can accept the following differential input levels :LVDS, LVPECL, CML
Integrated input terminal resistor
8-channel LVPECL output
The optional clock divisions are 1, 2, 4 and 8
Maximum input clock frequency :1GHz
Control the level of the LVCMOS interface input
Enable/Disable independent output through the I2C interface
Power-on status: All outputs are disabled
Output skew :60ps(maximum)
Output rise/fall time :350ps(maximum value)
Low additive phase jitter, root mean square :182fs(typical value)
Full 2.5V and 3.3V power supply voltages
Lead-free (RoHS 6) 32-pin VFQFN package
The operating temperature range is from -40°C to 85°C
The 8T73S208B-01NLGI is characterized by being powered by 2.5V and 3.3V power supplies. The guarantee of output-to-output and device-to-device skew characteristics makes the 8T73S208B-01NLGI highly suitable for clock distribution applications that require clear performance and repeatability. The integrated input terminal resistor simplifies the interface with the reference source and reduces the number of passive components. Under high impedance conditions, each output of the 8T73S208B-01NLGI can be enabled or disabled separately by the I2C register. When powered on, all outputs are disabled.
Application field
The 8T73S208B-01NLGI achieves buffering and distribution of clock signals through differential signals and is suitable for high-speed signal transmission scenarios, such as communication and data processing fields.
