DescriptionThe DS90CR218AMTD transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. The feature of DS90CR218AMTD are as follows: (1)20 to 75 MHz shift clock support; (2)50% duty cycle on receiver output clock; (3)best-in-class set & hold times on TxINPUTs and RxOUTPUTs; (4)low power consumption; (5)Tx + Rx Powerdown mode <400W (max); (6)±1V common-mode range (around +1.2V); (7)narrow bus reduces cable size and cost; (8)up to 1.575 Gbps throughput; (9)up to 197 Mbytes/sec bandwidth; (10)345 mV (typ) swing LVDS devices for low EMI; (11)PLL requires no external components; (12)rising edge data strobe; (13)compatible with TIA/EIA-644 LVDS standard; (14)low profile 48-lead TSSOP package.
The absolute maximum ratings of the DS90CR218AMTD are: (1)supply voltage: -0.3V to +4V; (2)CMOS/TTL input voltage: -0.5V to (VCC + 0.3V); (3)CMOS/TTL output voltage: -0.3V to (VCC + 0.3V); (4)LVDS Receiver input voltage: -0.3V to (VCC + 0.3V); (5)junction temperature: +150°C; (6)storage temperature range: -65°C to +150°C; (7)lead temperature(soldering, 4 sec.): +260°C; (8)maximum package power dissipation @ +25°C MTD48 (TSSOP) package: 1.89 W; (9)package derating: 15 mW/°C above +25°C; (10)ESD rating (HBM, 1.5kW, 100pF) > 7kV, (EIAJ, 0W, 200pF) > 700V, latch up tolerance @ 25°C > ±300mA.
The following is about the electrical characteristics of DS90CR218AMTD: (1)high level input voltage: 2.0V min and VCC max; (2)low level input voltage: GND min and 0.8V max; (3)high level output voltage: 2.7V min and 3.3V typical at IOH = -0.4 mA; (4)low level output voltage: 0.06V typical and 0.3V max at IOH = 2 mA; (5)input clamp voltage: -0.79V typical and -1.5V max at ICL = -18 mA; (6)input current: 1.8A typical and 10A max at VIN = 0.4V, 2.5V or VCC, -10A min and -0A typical at VIN = GND; (7)output short circuit current: -60mA typical and -120mA max at VOUT = 0V.
