7 Gb/s enabling various 120 Gb/s parallel PMD applications Global signal detect senses quiescent photocurrent with adjustable threshold and hysteresis Individual channel signal detect senses input signal strength (0MA) with adjustable sensitivity and hysteresis 20 uApp receiver sensitivity for 10-12 BER 180 mW per channel power dissipation for >500 mV differential output swing Serial digital interface for controlling channel power down, signal detect sensitivity, output amplitude and global signal detect Differential back-terminated outputs Flip-chip or direct wire-bond attach to photodiode 250-micron channel pitch matches optical ribbon fiber and array photodiodes • • Description The growing use of the Internet has created increasingly higher demand for multi-Gb/s I/O performance.
The demand for 100+ Gb/s WAN bandwidth fuels the growth of short-reach 120 Gb/s infrastructures within high-end telco and datacom routers, switches, servers and other proprietary chassis-to-chassis links.
The Zarlink PX6429 120 GB/s TIA/LA Receiver is a 12channel TIA/LA optical receiver designed for various 12x10 Gb/s, 10 Gb/s parallel optics and CWDM PMD applications.
It consists of a DC coupled transimpedance amplifier and an AC coupled differential limiting amplifier.
The transimpedance amplifier achieves a nominal 8 GHz bandwidth over a wide range of photodiode input capacitance.
Excellent channel-to-channel isolation ensures data integrity at the receiver sensitivity limits.
A global signal detect circuit provides the photodiode reverse bias voltage supply and senses average photocurrent supplied to the photodiode array.
The transimpedance amplifier is AC-coupled internally to a high-gain, high-bandwidth differential limiting amplifier.
