Product Information

XE5620 January 2003 56 KBPS Surface-Mountable Integrated Sealed-Hybrid Modem Description Xecom’s XE5620 provides a complete 56 KBPS modem into an miniature, surface-mount package. Xecom’s new HyPLCC™ package (Hybrid PLCC) makes it possible to meet the conflicting goals of small size, low cost and surface-mountability. The XE5620 targets remote monitoring applications in industrial, commercial and residential locations As a complete modem, the XE5620 includes not only all modem circuitry but also user transferrable FCC Part 68 Registration and UL60950 recognition. This allows the XE5620 to be easily integrated into your embedded application. Xecom’s new HyPLCC™ package infuses the XE5620 with both its small size and surface mountability. The HyPLCC package allows complex hybrid circuits to fit the 68-Pin PLCC footprint. The HyPLCC™ package provides a completely sealed environment protecting the XE5620 during assembly and board cleaning operations. Xecom also provides a low speed model, the XE2420, in the HyPLCC™ package. Features * Small Size: The HyPLCC™ measures less than 1 inch by 1 inch square and 0.290 inches thick * Surface-mountable: The HyPLCC™ package is equivalent to a 68-Pin PLCC device. * Data transfer at all rates from 300 BPS to 56KBPS using V.90, V.34bis, V.34, V.32bis, V.32, V.22bis, V.22, V.23, V.21, Bell 212A, and Bell 103 Protocols * Supports V.42 error correction and V.42bis Data Compression * Modem Control and Configuration via industry standard AT Commands. * Non-volatile memory stores modem configuration and permits stored number dialing. * Incorporates Fax send and receive capabilities controlled by Class 1 Fax commands. * Complete integrated DAA includes, Ring Detect, Loop Current Holding Circuit, Hook Switch. Metallic Surge Protection, and Solid-State DAA * User Transferrable FCC Part 68 Registration * UL60950 Recognition * Low Power operation, 3.3 Volts, 300 milliwatt; XE5620 BLOCK DIAGRAM XECOM (1) XE5620 XE5620 Mechanical Specifications b c a d i i g f e (TOP) e c .050” 45O i Millimeters Min Typ 7.11 7.24 25.02 25.15 24.13 24.26 23.11 23.37 1.15 1.27 17.65 17.78 10.03 10.16 0.13 0.25 Dimension a b c d e f g i(radius) Min 0.280 0.985 0.950 0.910 0.045 0.695 0.195 0.015 Inches Typ 0.285 0.990 0.955 0.920 0.050 0.700 0.200 0.020 Max 0.290 0.995 0.960 0.930 0.055 0.705 0.205 0.025 Max 7.37 25.27 24.38 23.62 1.40 17.91 10.29 0.38 XECOM (2) XE5620 XE5620 Pin Configuration /DCD /CTS RESET /DSR /RTS /DTR /RXD /TXD /RI GND SPKR N/C N/C Vcc N/C 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 24 23 22 21 RING N/C TIP N/C N/C NP NP NP NP TOP 20 19 18 17 16 Pin Descriptions PIN 1 NAME /DCD DESCRIPTION /DCD is an active low output from the modem. The AT&C command controls when the XE5620 asserts /DCD. /CTS is an active low output from the modem. The modem asserts /CTS to indicate that it can accept data from the terminal equipment on /TXD. RESET is an active low input which initiates a modem hardware reset. RESET must be active for a minimum of 100 milliseconds for a proper modem reset sequence. No external reset is required; if none is used the RESET signal should be left open. /DSR is an active low output from the modem. The AT&S command controls when the XE5620 asserts /DSR. /RTS is an active low input to the modem. /RTS indicates to the modem that the host has data to send. /DTR is an active low input to the modem. The AT&D command determines how the modem will interpret activity on /DTR. /RXD provides the path for received data and modem responses to be sent from the modem to the host terminal equipment. 2 /CTS 3 /RESET 4 /DSR 5 /RTS 6 /DTR 7 /RXD XECOM (3) XE5620 XE5620 Pin Descriptions (continued) PIN 8 NAME /TXD DESCRIPTION /TXD provides the path for transmitted data and modem commands to be passed from the host terminal equipment to the modem. The /RI signal reports on the presence of an incoming ring signal. When a ring occurs across Tip and Ring, the /...
