TG04-0366N1TR Datasheet:Figure 3 illustrates a simplified model of the typical ZL40518 and the application. The ZL40518 consist of an ideal switched current source and an equivalent model of the ZL40518 output stage. The Electrical Model for the Laser Diode is a Voltage source Vd (V_on) in series with the On Resistance Rd all in parallel with the Junction Capacitance Cd. This simplified model approximately represents the Laser Diode Electrical load when operated beyond the Laser Threshold. To a first approximation, the Optical output is proportional to the current flow in the Resistor Rd.TG04-0366N1TR Suppliers:POWER SUPPLIES Supply Voltage (AVDD and DVDD) Supply Voltage (OVDD) Supply Current IANALOG Supply Current IANALOG, Power-Down Supply Current IDIGITAL Supply Current IDIGITAL, Power-Down Dissipation Operation, Both Supplies Operation, Analog Supply Operation, Digital Supply Power-Down, Both Supplies Power Supply Rejection Ratio 1 kHz, 300 mV p-p Signal at Analog Supply Pins 20 kHz, 300 mV p-p Signal at Analog Supply PinsTG04-0366N1TR On stock:Architecture 20 MIPS* Burst Execution at 20 MHz 7.5 MIPS Sustained Execution at 20 MHz s 512-Byte On-Chip Instruction Cache Direct Mapped Parallel Load/Decode for Uncached Instructions s Multiple Register Sets Sixteen Global 32-Bit Registers Sixteen Local 32-Bit Registers Four Local Register Sets Stored On-Chip Register ScoreboardingThe SY100ELT25 is a differential ECL-to-TTL translator. Because ECL levels are used, a +5V, C5.2V (or C4.5V) and ground are required. The small outline 8- lead SOIC package and the single gate of the ELT25 makes it ideal for those applications where performance, space and low power are at a premium. The VBB output allows the ELT25 to also be used in a single-ended input mode. In this mode the VBB output is tied to the D input for a non-inverting buffer or the D input for an inverting buffer. If used the VBB pin should be bypassed to ground via a 0.01µF capacitor. NOTES 1Temperature ranges are as follows : A, B Versions: C40C to +85C, Y Version: C40C to +105C. 2Performance measured through full channel (SHA and ADC). 3See Terminology. 4Total Harmonic Distortion and Peak Harmonic or Spurious Noise are specified at C83 dBs for the AD7865-2. 5Measured between any two channels with the other two channels grounded. 6Sample tested @ +25C to ensure compliance. The P80CL31; P80CL51 (hereafter generally referred to as the P80CLx1) is manufactured in an advanced CMOS technology. The P80CLx1 has the same instruction set as the 80C51, consisting of over 100 instructions: 49 one-byte, 46 two-byte, and 16 three-byte. The device operates over a wide range of supply voltages and has low power consumption; there are two software selectable modes for power reduction: Idle and Power-down. For emulation purposes, the P85CL000 (piggy-back version) with 256 bytes of RAM is recommended. The FARM interfaces directly with worldwide AC mains and may be used with Vicor 1st or 2nd Generation 300V input DC-DC converters to realize an autoranging, high density, low profile switching power supply. The FARM includes a microcontroller that continuously monitors the AC line to control bridge/doubler operation. The user need only provide external capacitance to satisfy system hold-up requirements. |
