Overview

PSI2488-U9 is a GPON ONT SERDES capable of receiving serial data at the rate of 2.488Gbps and transmitting data at the rate of 1.244Gbps. The transmitter serializes 8 bit parallel data to a differential serial output, and the receiver de-serializes the differential serial data input to 16 bit parallel data output. The transmitter has a clock generator to generate clocks to serialize the data. The amplitude level of the TX output driver is programmable. There is a Squelch circuit at the receiver input to detect the loss of signal. Parallel loopback and serial loopback capabilities are implemented to be able to test the entire channel. To have more flexibility the reference clock can be any of 19.44, 38.8, 77.76 or 155.52MHz. A 2.5V power supply is used for the output stage of the TX output driver, and the rest of the IP has a flexibility to operate with either 1V or 1.2V supply. There is no external components such as resistors or capacitors used for the IP. Jitter tolerance and jitter generation of the IP is way beyond the jitter requirements making the IP suitable for very noisy environment. PSI2488-U9 is fabricated in UMC’s 90nm process.
