250 Mbps, Half-Duplex, Quad M-LVDS Transceivers

FEATURES

FUNCTIONAL BLOCK DIAGRAM

► Four M-LVDS transceivers (driver and receiver pairs)

► Switching rate: 250 Mbps (125 MHz)

► Independent pin select for each receiver, two modes:

► Type 1: input hysteresis of 15 mV typical

► Type 2: differential input threshold voltage offset by 100 mV to

support open-circuit, short-circuit, and bus idle fail-safe

► Compatible with the TIA/EIA-899 standard for M-LVDS

► Glitch free power-up/power-down on the M-LVDS bus

► Controlled transition times on the driver output

► Common-mode range: −1 V to +3.4 V, allowing communication

with ±2 V of ground noise

► Driver outputs high-Z when disabled or powered off

► Independent enable pins for each driver and receiver

► Enhanced ESD protection on bus pins

► ≥±15 kV HBM, air discharge

► ≥±8 kV HBM, contact discharge

► ≥±10 kV IEC 61000-4-2, air discharge

► ≥±8 kV IEC 61000-4-2, contact discharge

GENERAL DESCRIPTION

► Operating temperature range: −40°C to +105°C

► Available in 48-lead, 7 mm x 7 mm LFCSP

The ADN4680E comprises four multipoint, low voltage differential

signaling (M-LVDS) transceivers (driver and receiver pairs) that

can operate at up to 125 MHz, or 250 Mbps nonreturn to zero

(NRZ). The driver and receiver of each transceiver are connected in

half-duplex configuration, which allows each transceiver to be con-

figured via independent enable pins for either sending or receiving

data. Electrostatic discharge (ESD) protection of up to ±15 kV is im-

plemented on the bus pins. The transceivers are optimized for low

dynamic power consumption for use in high density applications.

The ADN4680E is designed to the TIA/EIA-899 standard for use in

M-LVDS networks and complement TIA/EIA-644 LVDS devices with

additional multipoint capabilities.

APPLICATIONS

► Backplane and cable multipoint data transmission

► Multipoint clock distribution

► Low power, high speed alternative to shorter RS-485 links

► Networking and wireless base station infrastructure

► Grid infrastructure and relay protection systems

► Differential extension of SPI networks

The receivers detect the bus state with a differential input of as little

as ±50 mV over a common-mode voltage range of −1 V to

+3.4 V. Each receiver can be independently pin selectable as a

Type 1 or Type 2 receiver. Type 1 receivers have 15 mV of hystere-

sis so that slow changing signals or loss of input does not lead

to output oscillations. Type 2 receivers exhibit an offset threshold,

guaranteeing the output state when the inputs are open (open

circuit fail-safe), the bus is idle (bus idle or terminated fail-safe), or

when the inputs are hard short circuited.

The device is available in a compact 48-lead, 7 mm × 7 mm LFCSP

and operates over a temperature range of −40°C to +105°C.
