Product Description
The Honeywell HRF-RX1000 is designed for 10 GB/s Ethernet Fiber Optic applications (IEEE 802.3), using the XAUI
standard interface. 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.

Product Architecture
The HRF-RX1000 product architecture, with four unique channels of photo diode receiver electronics and a common
set of bias voltage and Loss OF Signal (LOS) detection circuitry, is shown above. 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.

Capacitors C9-C16 allow the RF outputs to interface to an arbitrary common-mode level at the input of the retimer chip. 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 post-
amplifier 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.
