DS90CR285/DS90CR286 +3.3V Rising Edge Data Strobe LVDS 28-Bit Channel Link-66 MHz

Check for Samples: DS90CR285, DS90CR286

FEATURES

DESCRIPTION

The DS90CR285 transmitter converts 28 bits of

LVCMOS/LVTTL data into four LVDS (Low Voltage

Differential Signaling) data streams. A phase-locked

transmit clock is transmitted in parallel with the data

streams over a fifth LVDS link. Every cycle of the

transmit clock 28 bits of input data are sampled and

transmitted. The DS90CR286 receiver converts the

LVDS data streams back into 28 bits of

LVCMOS/LVTTL data. At a transmit clock frequency

of 66 MHz, 28 bits of TTL data are transmitted at a

rate of 462 Mbps per LVDS data channel. Using a 66

MHz clock, the data throughput is 1.848 Gbit/s (231

Mbytes/s).

Single +3.3V Supply

•

Chipset (Tx + Rx) Power Consumption <250

mW (typ)

•

Power-Down Mode (<0.5 mW total)

Up to 231 Megabytes/sec Bandwidth

Up to 1.848 Gbps Data Throughput

Narrow Bus Reduces Cable Size

290 mV Swing LVDS Devices for Low EMI

+1V Common Mode Range (Around +1.2V)

PLL Requires no External Components

Both Devices are Offered in a Low Profile 56-

Lead TSSOP Package

The multiplexing of the data lines provides

substantial cable reduction. Long distance parallel

single-ended buses typically require a ground wire

per active signal (and have very limited noise

rejection capability). Thus, for a 28-bit wide data and

one clock, up to 58 conductors are required. With the

Channel Link chipset as few as 11 conductors (4 data

pairs, 1 clock pair and a minimum of one ground) are

needed. This provides a 80% reduction in required

cable width, which provides a system cost savings,

reduces connector physical size and cost, and

reduces shielding requirements due to the cables'

smaller form factor.

Rising Edge Data Strobe

Compatible with TIA/EIA-644 LVDS Standard

ESD Rating > 7 kV

Operating Temperature: −40°C to +85°C

The 28 LVCMOS/LVTTL inputs can support a variety

of signal combinations. For example, seven 4-bit

nibbles or three 9-bit (byte + parity) and 1 control.
