i709x
General Description
The i7090 limiting amplifier, with complementary PECL data and signal detect
outputs, is designed for high speed fiber-optic based communications.
The i7090 also includes a programmable signal-level detector, allowing the user to
set
threshold at which the PECL outputs are enabled. Typically 1.75 dB(Optical) of
hysteresis is provided to prevent chattering when signal level is close to the threshold.
STB and JAM can be used to implement a squelch function, which gives fixed
logic levels at data outputs when the input signal is below the programmed threshold.
The i7090 has both PECL and CMOS status outputs (pins ST and STB).
