Low Skew, Low Additive Jitter, 8 output HCSL/LVDS/LVPECL ePPS Fanout Buffer

Key Features

- 3 to 1 input Multiplexer: Two inputs accept any differential (LVPECL, HCSL, LVDS, SSTL, CML, LVCMOS) or a single ended signal and the third input accepts a crystal or a single ended signal

- Eight differential HCSL/LVDS/LVPECL outputs

- Ultra-low additive jitter: 24fs (integration band: 12kHz to 20MHz at 625MHz clock frequency)

- Supports clock frequencies from 0 to 1.5GHz

- Supports 2.5V or 3.3V power supplies on HCSL/LVDS/LVPECL outputs

- Embedded Low Drop Out (LDO) Voltage regulator provides superior Power Supply Noise Rejection

- Maximum output to output skew of 50ps

- Device controlled via I2C or hardware control pins

- Factory configurable default settings via OTP

- Transparent for spread spectrum clock
