| CA3420AT CA3420AT PDF Case: All Copper Case and Components Hermetically Sealed Terminals: Contact Areas Readily Solderable Polarity: Cathode to Case(Reverse Units Are Available Upon Request and Are Designated By An R Suffix, i.e. PF2502R or PF2510R) Polarity: Red Color Equals Standard, Black Color Equals Reverse Polarity Mounting Position: Any CA3420AT Datasheet Intersil CA3089 is a monolithic integrated circuit that pro- vides all the functions of a comprehensive FM-IF system. The block diagram shows the CA3089 features, which include a three-stage FM-IF amplifier/limiter configuration with level detectors for each stage, a doubly-balanced quadrature FM detector and an audio amplifier that features the optional use of a muting (squelch) circuit. CA3420AT Suppliers NOTES: 1. See Test Conditions under TEST CIRCUITS AND WAVEFORMS. 2. This parameter is guaranteed but not production tested. 3. The bus switch contributes no propagation delay other than the RC delay of the ON resistance of the switch and the load capacitance. The time constant for the switch alone is of the order of 1.35ns at CL = 50pF. Since this time constant is much smaller than the rise and fall times of typical driving signals, it adds very little propagation delay to the system. Propagation delay of the bus switch, when used in a system, is determined by the driving circuit on the driving side of the switch and its interaction with the load on the driven side. 4. Minimums are guaranteed but not production tested. 5. Maximum toggle frequency for OE control input (pass voltage > VCC, VIN = 5V, RLOAD 1MΩ, no CLOAD). The CA3420AT is an ISDN data and telephony protocol engine which implements the lower level ISDN interface and communicates with the CMX605 and other standard devices to form a fully integrated ISDN chipset for both voice and data communications. It puts all the main data processing elements in one device, no ISDN software has to be written and simple Plug and Play design results. The CA3420AT supports one voice port, which can be used to provide ISDN telephony services or a POTS line interface, and one data channel, capable of operation at 115,200 b/s. It also has a full set of Hayes compatible AT command codes on its asynchronous data interface and keypad-configurable voice telephony services. Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maxi- mum Ratings² may cause substantial damage to the device. Functional operation of this device at other conditions beyond those listed in the specification is not implied and pro- longed exposure to extreme conditions may affect device reliability. M/A-COMs CA3420AT is designed to provide a low loss method of combining signals from six amplifiers or transmitters at PCS frequencies. High power internal components and an integral heat sink enables the device to combine non-coherant 20 Watt signals. Microstrip construction offers a design that is cost effec- tive and highly repeatable. ! Fully integrated, PLL-stabilized VCO ! Flexible frequency range from 800 MHz to 930 MHz ! ASK achieved by on/off keying of internal power amplifier ! FM possible with external varactor ! Wide power supply range from 2.2 V to 5.5 V ! High over-all frequency accuracy ! Very low standby current |
