| CA3420T-AS CA3420T-AS PDF CA3420T-AS Datasheet ATM Adaptation Layer Functions AAL1 mode (ITU-T I.363-1) and Circuit Emulation Service (ATMF AF-VTOA 0078.000): - Support for up to 256 AAL1 ATM VCCs - Support for structured and unstructured CES mode for 8 E1/T1/J1 links - Support for Channel Associated Signaling (CAS) - Built in SRTS (selectable) and ACM clock recovery methods CA3420T-AS Suppliers The Interface board provides those functions which would normally be included elsewhere in a GPS system. These functions include : voltage regulation, battery back-up (1000 hours memory retention), and serial interfaces to output the information and to input commands and DGPS correction data. The parts (B) and (C) of figure 3 give the voltage across the Transil and the current through it. It is important to note that the current flows through the protection device only during the clamping phase. This fact has to be taken into account when the protector is chosen, because the Received Data Output, push-pull CMOS driver output capable of driving standard CMOS or TTL loads. No external pull-up or pull-down resistor is required. Floating with a weak pull-up of 500 kΩ (typ.) in shutdown mode. The voltage swing is defined by the applied Vlogic voltage In the MR read mode the MR bias currents, set by the IRSET pin, are applied to the selected single stripe magneto- resistive head. The differential output voltage is amplified and output on the RDX and RDY pins. In idle or write modes these two outputs become high impedance, allowing wire-OR connection for multiple head/chip applications. The X25128 is a CMOS 131,072-bit serial EEPROM, internally organized as 16K x 8. The X25128 features a Serial Peripheral Interface (SPI) and software proto- col, allowing operation on a simple three-wire bus. The bus signals are a clock input (SCK) plus separate data in (SI) and data out (SO) lines. Access to the device is controlled through a chip select (CS) input, allowing any number of devices to share the same bus. |
