11 Funcional Descripion 3.3VIN and 5.0VIN 3.3VIN and 5VIN are he inpu power supplies for he. 3.3VIN powers he s inernal funcions; as well as, VCC, and VPP1 and VPP2. 5VIN provides power o VPP1 and VPP2. Tables 1 and 2 shows he conrol saes which supply is provided o which oupu C0, C1, C2 (Saes Conrols) C0, C1, and C2 conrol he oupu condiions for VCC, VPP1 and VPP2. C0, C1, and C2 are inpus o he provided by he hos. See Tables 1 and 2 for a complee lising. Also see he Applicaion Informaion secion. VCC VCC provides he main 3.3V supply o he CableCARD device. VCC is proeced agains high curren condiions and shor circuis. The minimum curren limi is se o 1.3A from 3.3VIN. Breakbefore-make swiching prevens crossed connecions during sae changes. The VCC oupu depends on he hos / card combinaion. See Tables 1 and 2 for a complee lising. Also see he Applicaion Informaion secion. VPP1, VPP2 (VPP1/2) VPP1 and VPP2 provide he 3.3V and 5.0V supplies o he CableCARD device. VPP1 and VPP2 are proeced agains high curren condiions and shor circuis. The minimum curren limi is se o a minimum of 150mA. Noe: VPP1 and VPP2 are powered separaely wih each having a curren limi of 150mA Break-before-make swiching prevens crossed connecions during sae changes. The VPP1/2 oupu depends on he hos / card combinaion. See Tables 1 and 2 for a complee lising. Also see he Applicaion Informaion secion. Sof-Sar The VCC, VPP1 and VPP2 oupus are all slew rae conrolled insuring a sof-sar urn-on characerisic. Sof-saring is in effec anyime a supply ramps from a 0V condiion or swiches beween volages, as in he case of he VPP oupus. Thermal Shudown Because elecrical fauls can cause significan heaing in power swiches, moniors is inernal emperaure and will shu down should he die emperaure reach 140 C. When he die emperaure has dropped by abou 10 degrees, will reacivae is oupus. If here is sill a problem, he effeced power swich will again ge ho, shuing off all oupus. This power cycling acion will coninue as long as he faul persiss. Once removed, will resume normal operaion. FAULT/ FAULT/ is a LOW rue open drain oupu which signals an over curren or over-emp condiion. As an open drain device, his oupu can be wire OR d wih oher FAULT/ oupus o a single inpu pin on he hos. For proper operaion his oupu mus be pulled-up o he logic supply rail by an exernal resisor. This resisor can be large in value, bu no so large ha leakage currens caused by surface conaminaion can cause a false indicaion of a faul condiion. For his reason i is recommended ha he pull-up resisor be 300kΩ or less. FAULT/ is delayed wih respec o an over curren condiion being deeced. This is o preven brief curren spikes from riggering an inerrup o he sysem hos. The delay is on he order of 12ms. Any faul lasing over 8 ms riggers he FAULT/ oupu. There is no delay for hermal fauls. Any over-emp condiion is repored immediaely. UVLO (Under Volage Lockou) An under-volage lock ou (UVLO) circui moniors he 3.3VIN rail and keeps disabled unil he inpu volage reaches he minimum level needed for proper operaion. Below his volage he oupu swiches are OFF and all funcionaliy is disabled. Sepember M C

13 Applicaion Informaion Figure 1 shows S-Mode power sae diagram. CableCARD Operaing Modes The OpenCable sysem has a hos componen (S-Hos or M-Hos) and a card componen (S-Card or M-Card). The hos / card combinaion deermines which operaional mode is used i.e. S-Mode or M-Mode. This in urn deermines he appropriae sae diagram. Table 3 below shows all of he combinaions and operaing modes. S-Hos M-Hos S-Card S-Mode S-Mode or No power M-Card S-Mode M-Mode Table 3 Operaing Mode Combinaions An M-Hos has he choice o accep or no accep an S- Card. If he M-Hos acceps he S-Card hen he M-Hos will iniiae a change from M-Mode o S-Mode. Oherwise, he M-Hos will no power-up he S-Card. S-Hos Afer power-up, he S-Hos remains in sae 0 [000] unless one of wo evens occurs: 1. CIS Reques The CableCard may reques ha he Vpp oupus be provided wih 5VIN, ha is, ener sae 1 [001]. I is he S-Hos decision wheher o provide he Vpp oupus wih 5VIN. The S-Hos has wo possible opions. a. If he S-Hos refuses o provide 5VIN, hen he S-Hos does no change o sae 1 [001] and will remain in sae 0 [000], even upon card removal. See paragraph 2 below. b. If he S-Hos grans 5VIN, hen S-Hos changes o sae 1 [001]. The S-Hos remains in sae 1 [001] wihou reurning. See paragraph 2 below. 2. Card removal Upon card removal, he S-Hos has wo possible opions: a. The S-Hos changes direcly o sae 0 [000], regardless of he sae a card was removed. b. The S-Hos has he opion o pass hrough sae 6 [110] o remove any excessive volage or charge on he Vpp oupus. The S-Hos hen reurns o sae 0 [000]. Figure 1 S-Hos Power Sae Diagram M-Hos 1. Power-up - Upon power-up, M-Hos wo opions: a. Move direcly he sae 2 [010] b.

Card Deecion If he M-Hos deecs ha he insered card is an M-card, hen he M- Hos will change o sae 3 [011]. This informs he card ha he hos is an M-Hos. 4. Card ID The M-Hos uses he card idenificaion process o deermine wha ype of card i is and wha modes he card can operae in. There are hree opions: a. If he card is an M-Card, hen he M- Hos will change o sae 4 [100] and remain in sae 4 [100] unil card removal. b. If he card is an S-Card able o suppor CH1, hen he M-Hos will rese he card and power-up in S-Mode. The card will remain in S-Mode unil card removal. c. If he card is no an M-Card, or an S- Card no able o suppor Ch1, hen power will no be provided o he card. The card will remain wihou power and no change sae unil card removal. Sepember M C
