SN65LVDS20 4Gbps PECL 至 LVPECL 中继器
The SN65LVDS20 and SN65LVP20 are a high-speed differential receiver and driver connected as a repeater. The receiver accepts low-voltage positive-emitter-coupled logic (PECL) at signaling rates up to 4 Gbps and repeats it as either an LVDS or PECL output signal. The signal path through the device is differential for low radiated emissions and minimal added jitter.
The outputs of the SN65LVDS20 are LVDS levels as defined by TIA/EIA-644-A. The outputs of the SN65LVDP20 are compatible with low-voltage PECL levels. A low-level input to EN enables the outputs. A high-level input puts the output into a high-impedance state. Both outputs are designed to drive differential transmission lines with nominally 100-
characteristic impedance
