Implemented using Honeywell's patented Silicon On Insulator (SOI) manufacturing technology, the HRF-RX1000 integrates four channels of 3.125 Gb/s photo diode receiver, each channel containing trans-impedance amplifiers, AGC, limiting amplifiers, and XAUI drivers, all onto a single integrated circuit. The HRF-RX1000 operates from a single 3.3V power supply, provides excellent sensitivity, extremely high channel to channel isolation, offset compensation, and supports a direct interface to XAUI-XAUI re-timers. Independent Loss Of Signal (LOS) and automatic channel power-down functions are internally implemented. A very high level of integration minimizes the need for external components.

The external components such as power supply de-coupling and RF chokes are not shown. Each channel of the HRF-RX1000 incorporates a separate Automatic Gain Control (AGC) with a number of discrete settings. The Loss Of Signal (LOS) function operates independently for each channel. When LOS is detected on a channel, most of the circuits associated with that channel are powered down and the differential output voltage goes to zero. The data outputs may not become valid until some time after the negation of the LOS.

DC coupled termination to VDD is permitted but DC coupled termination to GROUND is not. The HRF-RX1000 requires external power supply filtering for correct operation. Contact Honeywell for technical insights on the best approaches. The front-end power supply requires completely independent filtering of channel groups 1/2 and 3/4. The postamplifier supply AVDD1 uses a common filter but it is recommended that the power routing for AVDD1A and AVDD1B on the PCB from the inductor L3 to the bypass capacitor C3 and C4 is independent. Some form of low-frequency regulation is also assumed but the exact nature of this is not critical. Odd numbered bypass capacitors should be located at the `B' side of the HRF-RX1000. Even numbered bypass capacitors should be located at the `A' side of the HRF-RX1000. An allowance for the DC voltage drop across the inductors specified above has been included within the on-chip supply voltage budget below.
