2 / 28 page OBSOLETE LM1229 SNOSAH0D – MARCH 2005 – REVISED APRIL 2013 www.ti.com DESCRIPTION (CONTINUED) he Deflection section uses a 12.0 MHz resonator and with it the horizontal processor is capable of locking to seven different television signal formats, 15.734, 28.1, 31.468, 33.7, 37.9, 45.0, and 48.08 kHz by configuring two external tri-state pins. The resonator frequency can be scaled up or down by as much as 5% to accommodate custom scan frequencies, however all scan modes will be scaled up or down by the same percentage. Additional inputs are provided for H and V synchronization, X-Ray protection, V scan protection, and H and V EHT compensation. Deflection output signals are provided for horizontal drive, variable amplitude vertical ramp, vertical ramp reference voltage, variable amplitude dynamic focus, and E-W correction with DC level adjustment for size. A status register is also provided for the system microcontroller to read and check for failure conditions. The IC is packaged in an industry standard 64 lead LQFP molded plastic package. LM1229 Package and Pinout Top View Figure 1. 64-Pin Non-Exposed DAP - TQFP Package See Package Number PAG0064A Exposed DAP – HTQFP Package See Package Number PAP0064A These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. 2 Submit Documentation Feedback Copyright © 2005–2013, Texas Instruments Incorporated Product Folder Links: LM1229 |
