4. Specification of Receiver

Parameter	Symbol	Min.	Typ.	Max.	Unit	Note
Input Optical Wavelength	λIN	1480		1600	nm	PIN-PD
Receiver Sensitivity	PIN			-31	dBm	Note (1)
Input Saturation Power (Overload)	PSAT	-3			dBm
LOS-Deassert Power	PA	-		-31	dBm
LOS-Assert Power	PD	-44			dBm	Note (2)
LOS Hysteresis	PA-PD	0.5	2	5	dB
Optical Reflectance				-14	dB	Note (3)
Output Data Rise/Fall time	tr/tf			1.5	ns	Note (4)
S/X Endurance				10	dB	Note (5)
Optical Isolation		25			dB	Note (6)

Note (1). Measured with 1520nm, ER=10dB; BER =<10-10@PRBS=223-1 NRZ Note (2). When LOS asserted, the data output is Low-level (fixed)

Note (3). When the terminal is viewed from the optical path, the reflection toward the optical path of the optical signal with a central wavelength of 1480nm to 1580nm transmitted to terminal.

Note (4). These are 20%~80% values

Note (5). X=10 MHz, Rectangular BER =10-10

Note (6). Receiver isolation between 1260nm ~1360nm

Total Supply Current	ICC			A	mA	Note (1)
Differential Data Input Swing	VDT	500		2400	mVp-p
Differential line input Impedance	RIN	80	100	120	Ohm
Transmitter Disable Input-High	VDISH	2		VCC	V	Note (2)
Transmitter Disable Input-Low	VDISL	0		0.8	V
Transmitter Fault Output-High	VTXFH	2		VCC+0.3	V
Transmitter Fault Output-Low	VTXFL	0		0.8	V
Transmitter Fault Pull up Resistor	RTX_FAULT	4.7		10	kΩ	Note (3)
Receiver
Total Supply Current	ICC			B	mA	Note (1)
Differential Data Output Swing	VDR	400		2000	mVp-p	Note (4)
LOS Output Voltage-High	VLOSH	2		VCC+0.3	V
LOS Output Voltage-Low	VLOSL	0		0.8	V
Receiver LOS Load	RRXLOS	4.7		10	kΩ	Note (3)

Note (1). A (TX)+ B (RX) = 300mA

(A: Not include termination circuit; B: using a resister of 150Ω between Data-output and ground) Note (2). There is an internal 4.7 to 10kΩ pull-up resistor to VccT.

Note (3). Pull up to VCC on host Board.

Note (4). Internally AC coupled with LVPECL output, but requires a 100Ohm differential termination at or internal to Serializer/ Deserializer.
