PAL16R8PC Datasheet
PAL16R8PC Price GENERAL DESCRIPTION The DS2149 is a fully integrated LIU for long- haul or short-haul Tl applications over twisted- pair installations. It interfaces to two twisted-pair lines-one pair for transmit and one pair for receive through an appropriate network interface. The device can be configured for control through software or hardware mode. Software control is accomplished over a serial port, in hardware mode; individual pin settings allow standalone operation. The device provides a precise, crystal-less jitter attenuator that can be placed in either the transmit or receive path. PAL16R8PC on stock - Typical Active Current: 0.5 mA @ f = 1 MHz - Typical Active Current: 1.5 mA @ f = fmax (70 ns speed) Low standby power Easy memory expansion with CE and OE features . Automatic power-down when deselected CMOS for optimum speed/power If RESET# is asserted during a program or erase operation, the RY/BY# pin remains a "0" (busy) until the internal reset operation is completed, which requires a time of tREADY (during Embedded Algo- rithms). The system can thus monitor RY/BY# to determine whether the reset operation is completed. If RESET# is asserted when a program or erase operation is not executing (RY/BY# pin is "1"), the reset operation is completed within a time of tREADY (not during Embedded Algorithms). The system can read data after the RESET# pin returns to VIH, which requires a time of tRH. |
