+ | == FXS == | ||
+ | |||
+ | We have a companion FXS rack device, Audio Codes MP-124D/ | ||
+ | |||
+ | === Components === | ||
+ | |||
+ | * Main MCU: PowerQUICC MPC860PZQ80D4 | ||
+ | * Line interface: 12x PEB3264 and PEB4266 | ||
+ | * Custom ASICs (codecs?): 6x AC482-C (three more footprints unpopulated) | ||
+ | |||
+ | === PSU Recap === | ||
+ | |||
+ | The caps on the PSU (APSI-605AC Rev.C) are bad. Here's the values jotted down so that q3k can order some new ones: | ||
+ | |||
+ | * C9: 470uF 63V | ||
+ | * C10: 470uF 63V | ||
+ | * C14: 470uF 63V | ||
+ | * C15: 220uF 100V | ||
+ | * C17: 220uF 100V | ||
+ | |||
+ | 470uF/63V caps are 20mm tall, 16 mm diameter, 7mm leg pitch. 220uF/100V caps are 25mm tall, 16mm diameter, 7mm leg pitch. The board came with Nichicon branded caps. C19 is visible bulged. C10 is burst. The rest look fine, but should be replaced regardless. | ||
