The PI90LV048A/PI90LVT048A quad flow-through differential line
receivers are designed for applications requiring ultra low-power
dissipation and high data rates. The device is designed to support
data rates in excess of 500 Mbps (250 MHz) using Low Voltage
Differential Signaling (LVDS) technology.
500 Mbps (250 MHz) switching rates
Flow-through pinout simplifies PCB layout
150ps channel-to-channel skew (typical)
100ps differential skew (typical)
2.7ns maximum propagation delay
3.3V power supply design
High impedance LVDS inputs on power down
Low Power design (40mW, 3.3V static)
Wide common-mode input voltage range: 0.2V to 2.7V
Accepts small swing (350mV typical) differential signal levels
Supports open, short and terminated input fail-safe
Low-power state when in fail-safe
Conforms to ANSI/TIA/EIA-644 Standard
Industrial temperature operating range (–40°C to +85°C)
Available in SOIC and TSSOP package
The devices accept low-voltage (350 mV typical) differential input
signals and translates them to 3V CMOS output levels. The receiver
supports a 3-state function, which may be used to multiplex outputs,
and also supports open, shorted and terminated (100 ohms) input failsafe. The receiver output will be HIGH for all fail-safe conditions.
PI90LVT048A features integrated parallel termination resistors
(nominally 110 ohms) that eliminate the requirement for four discrete
termination resistors and reduce stud length. PI90LV048A inputs
are high impedance and require an external termination resistor
when used in a point-to-point connection. The devices have a flowthrough pinout for easy PCB layout.
The EN and EN inputs are ANDed together and control the 3-state
outputs. The enables are common to all four receivers. The
PI90LV048A and companion LVDS line driver (eg. PI90LV047A)
provide a new alternative to high-power PECL/ECL devices for
high-speed point-to-point interface applications.

Notes
1.
“Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. They are not meant to imply
that the devices should be operated at these limits. The table of “Electrical Characteristics” specifies conditions of device operation.
2.
Current into device pins is defined as positive. Current out of device pins is defined as negative. All voltages are
referenced to ground unless otherwise specified.
3.
All typicals are given for: VCC = +3.3V, TA = +25°C.
4.
Generator waveform for all tests unless otherwise specified: f =1 MHz, ZO =50 ohms, tr and tf (0% to 100%) ≤ 3ns for RIN.
5.
The VCMR range is reduced for larger VID. Example: if VID = 400mV, the VCMR is 0.2V to 2.2V. The fail-safe condition with inputs
shorted is not supported over the common-mode range of 0V to 2.4V, but is supported only with inputs shorted and no external commonmode voltage applied. A VID up to VCC – 0V may be applied to the RIN+ /RIN– inputs with the Common-Mode voltage set to VCC/2.
Propagation delay and Differential Pulse skew decrease when VID is increased from 200mV to 400mV.
Skew specifications apply for 200mV ≤VID ≤800mV over the common-mode range .
6.
tSKD1 is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the
same channel
7.
tSKD2, Channel-to-Channel Skew is defined as the difference between the propagation delay of one channel and that of the others on the
same chip with any event on the inputs.
8.
tSKD3, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification
applies to devices at the same VCC, and within 5°C of each other within the operating temperature range.
9.
tSKD4, part to part skew, is the differential channel-to-channel skew of any event between devices. This specification applies
to devices over recommended operating temperature and voltage ranges, and across process distribution. tSKD4 is defined as |Max–Min|
differential propagation delay.
10. ESD Ratings: HBM (1.5 kohms, 100pF) ≥10kV
EIAJ (0 ohm, 200pF) ≥1200V
11. Output short circuit current (IOS) is specified as magnitude only, minus sign indicates direction only. Only one output should be shorted at
a time, do not exceed maximum junction temperature specification.
12. CL includes probe and jig capacitance.
13. VCC is always higher than RIN+ and RIN– voltage. RIN– and RIN+ are allowed to have a voltage range –0.2V to VCC – V ID/2. However, to be
compliant with AC specifications, the common voltage range is 0.1V to 2.3V
14 f MAX generator input conditions: t r = t f <1ns (0% to 100%), 50% duty cycle, differential (1.05V to 1.35V peak to peak).
Output criteria: 60/40% duty cycle, VOL (max 0.4V), VOH (min 2.7V), Load = 15pF (stray plus probes).
